Is it a crime to shoot a kidnapper who is in the process of kidnapping your child? If someone was in the process of kidnapping your baby and you were chasing after that person, if you have a gun on you and you use it to shoot that person and then that person dies, would you be charged with murder?
What you are charged with - murder and the appropriate degree, manslaughter, felony assault or other crime - depends on the local or federal prosecutor (and possibly a grand jury), the jurisdiction and how the prosecutor views the evidence; and if the prosecutor feels they can win a conviction against you in front of a jury for the charges. The prosecutor will look at the evidence and try to determine your motive and what actually happened: did you want to kill the kidnapper, i.e. use deadly force to stop the crime? Did you only want to wound the kidnapper and save your baby? Did you only want to wound the kidnapper but inadvertently killed him/her? Was it possible to stop the kidnapping without using force at all? Did you first try to stop the kidnapping without deadly force and then resort to shooting the kidnapper? Did you endanger others in the area by shooting? Those details all factor into the prosecutor's decision on which of the different degrees of murder, manslaughter, etc., to charge the parent with (or, not charge). See What Is Manslaughter? What Is Murder vs. Manslaughter? | Nolo.com. Once the prosecutor decides on charges, they will try and win a conviction against you in front of a jury for the charges. The prosecutor could possibly decide that the case already been tried in the court of public opinion - the person saving their baby and shooting a criminal is too sympathetic to charge with a crime - and there is no use in bringing charges and not getting a conviction from the jury. Or, the prosecutor could decide that you were legally defending yourself and family and potentially deadly force was justified; this will greatly depend on jurisdiction, i.e. the different types of "Stand Your Ground" laws or other similar laws regarding self-defense in different states. You may be confusing the idea of being charged with a crime and actually being of a convicted of a crime. The prosecutor can charge you with a crime and take you to court, but unless the jury convicts you on the basis of evidence, you won't be convicted.
Would any offence be committed for: Having this on your person? Buying or selling this? Leaving it around for people to plug in to a computer? In the abstract, I don't think that this conduct would violate either Section 36 of the U.K. law or U.S. law, although, obviously, purposefully destroying a computer itself (i.e. actually using the device without the consent of the owner of the computer) would violate many U.K. laws and would also violate many U.S. laws at both the state and federal level. I also don't think that possession or buying or selling this product would be a crime absent some intent that it be used illegally, in which case there might be an "attempt" to commit a crime offense, or an offense that would make one part of a conspiracy to commit a crime. In the "leaving it around" example, there is arguably an intent to use it to harm another improperly, although the phrasing is ambivalent. While many statutes in the U.S. criminalize possession of burglary tools, or drug paraphernalia, sometimes with an associated intent element (although even these crimes often have an express or judicially implied intent to use element), I'm not aware of any statute that criminalize possession of tools for malicious destruction of property. So, if the tools aren't possessed or used in a manner intended as a step in the facilitation of a crime, I don't think that any law is violated. So far as I know, the U.S. does not have a counterpart to Section 37 of the British statute cited above (it isn't a terribly easy thing to search for to definitively rule out the existence of such a law because federal law has many uncodified crimes in unexpected statutes and there are many sets of state criminal statutes, not all of which are codified either). The example giving in the comments by @gnasher729 of possession of a hammer which could be used to do the same things that this object could be used to do is instructive. Arguably, this USB-like tool is more specifically targeted at malicious conduct. But, for example, when I used to work as a radio news reporter, we had a machine that was basically a high powered magnet that was specifically designed to destroy all information on magnetic media. This was, in part, so that it could be reused, but it was also so that confidential interviews wouldn't fall into the wrong hands once they were no longer needed, in much the way that one might shred paper documents. It isn't so implausible to think that a device like this one might be necessary for individuals or firms with national defense secrets embedded in their hardware and software to have on hand in order to destroy a sensitive computer in order to prevent a security breach, if necessary. In a case like that, leaving one of these devices around the office unlabeled might be negligent, but wouldn't have the intent necessary to be an intended crime. And, it is hard to imagine that the device itself, which seems pretty simple, would itself involve any technology that is a national security secret, so it probably wouldn't violate export control laws. Of course, possession, purchase or sale of such a specialized device, or leaving it around unlabeled would certainly be powerful evidence of an intent to use the device in a wrongful manner, and hence, of an attempt to commit a crime. Indeed, possession of such a device or purchase of one might very well be sufficient to establish probable cause to seize the device and arrest the person holding it on charges of an attempt to destroy a computer. But, this device would be merely powerful evidence of an intent to commit a crime, rather than something that is a crime to commit in and of itself. There are no international laws that govern this kind of thing. The only international laws applicable to individuals pertain to war crimes and nuclear and chemical weapons. Even then, most international laws direct member nations to adopt domestic laws on the subject rather than being self-executing.
Exactly the same thing that stops the same rogue lawyer from putting on a mask and robbing a bank. One is the crime of fraud and the other the crime of armed robbery but they are both crimes. People commit crimes all the time; that is why nearly 1 million people in the U.S. are in jail right now - some of them may even be in there for crimes they actually committed! Were your lawyer to commit this crime he may get caught or he may not; if he does he's going away for a long time and can never work as a lawyer again. So it's simply a matter of risk assessment; oh, and ethics
The term doesn’t come up Because, AFAIK, there are no circumstances where being ignorant of the law allow a person to escape culpability. There are, however, laws that allow ignorance of the facts to be an excuse. For example, a person who receives stolen goods where it is reasonable to believe that they aren’t is not guilty of the crime (although the still don’t own the goods).
The stated facts are an almost carbon copy of the facts in R v Dudley and Stephens (1884) 14 QBD 273 DC so we know the answer - No The court ruled that cannibalising the boy was not urgently necessary. Even though the cabin boy would almost certainly have died of natural causes, the sailors killed the boy intentionally and were guilty of murder. There was some degree of necessity arising from the threat of starvation but, at any moment, a ship could have sailed over the horizon to save them as, indeed, the three were rescued. Since they could never be sure that the killing was actually necessary from one minute to the next, the defence was denied. Specifically, cannibalism is not the crime; murder is. Necessity requires: an urgent and immediate threat to life which creates a situation in which the defendant reasonably believes that a proportionate response to that threat is to break the law. In practice, necessity is only a defence to relatively minor crimes, like breaking traffic rules in a race to a hospital or breaking a window to escape a burning building - the consequences of the breach have to be relatively trivial in relationship to the consequences of adhering to the law.
In the USA communication between an attorney and their client is "privileged". This makes it illegal for, amongst other things, the police to listen in to conferences between a suspect and their attorney. However in practice there is often little to prevent the police actually doing so.
If I remember the case correctly, he didn't make his home look uninhabited (that is nobody is living there) but as if the inhabitants had left (gone shopping etc.) to make it look attractive to burglars. He then waited inside, armed with a gun, with the intent of shooting any burglars that might arrive. He shot the first burglar in the legs, and then proceeded to kill the unarmed and now defenseless burglar, who was lying injured on the ground and was in no position anymore to hurt him. He then did the same with a second burglar, shooting her in the legs, then shooting her multiple times, and when he found she was still alive, he shot her point blank in the face while she was lying on the ground. You are asking the wrong questions. You are asking "is it illegal to remove a truck". It's not. What is illegal is to intentionally create a situation where you shoot people and try to claim "self defence". It can very well be argued that by luring burglars into your home with the intent to kill them, they are not actually illegal in that home, because you wanted them to be there. You can do many things that are each completely innocent but add up to a crime. Actually, for everyone interested, I posted a question maybe last week or the week before whether you can be convicted for both first degree murder and second degree murder for killing a person, and it was exactly this case that inspired the question. What should he have done? If he hadn't lured the burglars in, I believe the case would have still been a double murder, since he killed both unarmed teenagers when they were absolutely no threat. It might not have been first degree murder since it would not have been premeditated. But he intentionally lured them in, making it premeditated (first degree) murder. If he had only injured them, the fact that he lured them in could very likely have made this an assault. You asked: "Now that the burglars are in his house, what should he have done? " Well, he got himself into a dangerous situation. Remember, he was convicted for premeditated murder. So just before he shot the girl in the head, he should have instead put the gun away and called police and an ambulance. It would have been one murder instead of two. Just before he shot the boy, he should have put the gun away and called police and an ambulance. It would have been just attempted murder. When he heard the first person entering, he should have called the police and waited. When the burglar came in sight, he should not have shot and injured him. It's a similar question to "if I try a bank robbery and there is an armed guard, what should I do". The only legal thing to do is to drop your weapon and wait to be arrested. If an armed burglar had appeared instead of two unarmed teens, well, he would have put himself into a dangerous situation. Just as the burglar would have no right to shoot even if a home owner points a weapon at him, he had no right to shoot, no right to self defense, since he had intentionally created the situation. Tough shit. That's what you may get if you plan a murder. Responding to some comments: @J.Chang Are you being serious? You are not allowed to make your house inviting to burglars, while waiting inside with the intent of killing them. Self defense only applies when a reasonable person would believe they are in danger. Reasonable persons don't think that a burglar comes in with the intent of blowing themselves up and taking the home owner with them. And no, you don't get to "assume the worst". Not when the worst is something no reasonable person would expect. Thanks to Dale for pointing out that even for soldiers in a war situation, where different rules apply, deliberately killing a helpless enemy combatant is murder.
We're missing a lot of facts that would help drive the analysis. The first question I'd ask was whether this was part of an actual or attempted sex offense. If that's the case, the suspect could be facing particularly serious charges. Other information is also missing, such as the drug involved, whether it's on the list of controlled substances, her knowledge of the drug, her relationship to the suspect, and so on. Still, based on the information we've got and the inferences we can make from them, I could reasonably see the following charges being filed: Sec. 12-3. Battery. (a) A person commits battery if he or she knowingly without legal justification by any means (1) causes bodily harm to an individual Sec. 12-3.05. Aggravated battery. (g) Offense based on certain conduct.

(2) Knowingly administers to an individual or causes him or her to take, without his or her consent or by threat or deception, and for other than medical purposes, any intoxicating, poisonous, stupefying, narcotic, anesthetic, or controlled substance, or gives to another person any food containing any substance or object intended to cause physical injury if eaten. Sec. 12-4.5. Tampering with food, drugs or cosmetics.

Sec. 21-1. Criminal damage to property. (a) A person commits criminal damage to property when he or she: (1) knowingly damages any property of another Sec. 11-1.20. Criminal sexual assault. (a) A person commits criminal sexual assault if that person commits an act of sexual penetration and: (2) knows that the victim is unable to understand the nature of the act or is unable to give knowing consent; Sec. 11-1.30. Aggravated Criminal Sexual Assault. (a) A person commits aggravated criminal sexual assault if that person commits criminal sexual assault and any of the following aggravating circumstances exist during the commission of the offense or, for purposes of paragraph (7), occur as part of the same course of conduct as the commission of the offense: (2) the person causes bodily harm to the victim, except as provided in paragraph (10); (3) the person acts in a manner that threatens or endangers the life of the victim or any other person; (4) the person commits the criminal sexual assault during the course of committing or attempting to commit any other felony; (7) the person delivers (by injection, inhalation, ingestion, transfer of possession, or any other means) any controlled substance to the victim without the victim's consent or by threat or deception for other than medical purposes; Sec. 11-1.50. Criminal sexual abuse. (a) A person commits criminal sexual abuse if that person: (2) commits an act of sexual conduct and knows that the victim is unable to understand the nature of the act or is unable to give knowing consent. Sec. 11-1.60. Aggravated criminal sexual abuse. (a) A person commits aggravated criminal sexual abuse if that person commits criminal sexual abuse and any of the following aggravating circumstances exist (i) during the commission of the offense or (ii) for purposes of paragraph (7), as part of the same course of conduct as the commission of the offense: (2) the person causes bodily harm to the victim; (5) the person acts in a manner that threatens or endangers the life of the victim or any other person; (6) the person commits the criminal sexual abuse during the course of committing or attempting to commit any other felony; or (7) the person delivers (by injection, inhalation, ingestion, transfer of possession, or any other means) any controlled substance to the victim for other than medical purposes without the victim's consent or by threat or deception. Sec. 9-1. First degree Murder (a) A person who kills an individual without lawful justification commits first degree murder if, in performing the acts which cause the death: (2) he knows that such acts create a strong probability of death or great bodily harm to that individual or another; or (3) he is attempting or committing a forcible felony other than second degree murder.
