What happens if a murder occurs in space? Let's say that there's a joint mission to the International Space Station, composed of American and British astronauts. They get along well for the first few days, but tensions grow, and eventually an American crew member kills a one of the British group. How would the investigation and trial be conducted? Who would investigate? What court would the defendant be tried in? Is there some kind of "space rulebook" that spells out what to do with murder, or crime in general?
Maritime law applies in space which means jurisdiction lies with the country of registration of the vessel. So, if the crime occurs in transit then Russia has jurisdiction since, at present, all transportation is provided by Russian Soyuz capsules. The ISS itself is governed by a number of international treaties, MOU and bi-lateral agreements. In essence: The basic rule is that 'each partner shall retain jurisdiction and control over the elements it registers and over personnel in or on the Space Station who are its nationals' (Article 5 of the Intergovernmental Agreement).
After the edit of the question: Deceased defendants are not normally put on trial. Before the edit of the question: The ability of the US President to start military operations is a somewhat murky issue. Congress has the power to declare wars, the President is the commander in chief, and the War Powers Resolution complicates things. But this is not really an issue because Congress approved the operation. As far as domestic US law, the war was legal. I'm not aware of any competent legal authority deciding on the invasion being a crime of aggression under international law. The practical problem here is that such trials mostly happen under UN auspices at the end of a world war, putting the defeated side on trial. The UNSC would probably be involved, and the US is a veto power. Note also that Iraq had probably violated the ceasefire agreement from 1991 ... Which leaves the domestic issue of lying to the American public and especially to Congress. While perjury in a congressional hearing may be a crime, proving it would require a legal judgement of the state of knowledge at the time the supposed perjury happened. To a large degree, the US government deceived itself before it gave testimony, and being factually wrong is not perjury if the witness believed what he or she said.
All Four of them! Double Jeopardy is not in play if a jurisdiction can lay claim to your criminal action, so if you stand on the Four Corners and shoot a man in any of the four states, each state has a right to charge murder. In addition, the Federal Government can have a go at you because you crossed state lines while in comission of a crime. Plus the Navajo Nation, which controls the reservation land the border is on. So that six separate charges. That said, the state the dead body occupied at time of Murder would have the best case for action and the other three would likely let that state try you first. The Feds would only step in if each of the four states failed to convict, though they can step in whenever they want (they are just watching to see if you'll serve time first). Not sure at which point Tribal jurisdiction applies, but given that this is a fairly common Jurisdiction issue, I'm sure it's been worked out.
In this specific case and location, the precise location of the incident was explicitly made a public space via state law not too long before this actual event. They therefore most certainly have no right to privacy. What is interesting to me though is the other side of this, does someone have the right to record others in public spaces, or is it simply not illegal? For instance if I non-destructively and non-violently "jam" your camera by shooting a low-power IR beam at your lens, have I abridged a legal right of yours? I don't think it would be illegal to do this. I am not even positive its against the 1st Amendment. The 1st Amendment relates only to the dissemination of information, not the collection of it. The Constitution doesn't seem to compel the gov't to make information available, or even to make things/events/spaces observable. The various "sunshine" laws after-all had to be enacted, it wasn't part of an interpretation of the 1st Amendment. To put a finer point on it, is recording events in public spaces legal or merely lawful?
"Police" that one would generally encounter in the US are local or state agencies, and the ordinary crimes you mentioned are matters of state law, so they would be reported to local or state police. (There are federal law enforcement agencies, but they only deal with specialized areas of federal law, and you wouldn't ordinarily encounter them in daily life.) On the other hand, immigration is a matter of federal law. The responsibilities of local or state police are governed by state law, and the federal government cannot compel state officers to enforce federal law. A specific state's law could potentially require state and local police to ask about people's immigration status and/or ask the federal government to check on the status of someone they suspect might be illegal. I believe a few red states have enacted, or are considering, such laws, though they usually deal with people stopped by police rather than people filing a report. Some of these laws have been challenged in court, and I am not sure which exact parts of which laws are still being implemented for each of those states. Most states do not have such laws.
There are many cases where it is quite obvious that A has illegally killed B, but where it is much less obvious whether this was first degree murder, second degree murder, or manslaughter. The usual approach is to charge A with all three, and then convict for the highest that the jury agrees with (for example, the jury might agree that it was at least second degree murder, but not agree that it was first degree murder beyond reasonable ground). A prosecutor who wants a first degree murder conviction might charge with first degree murder only, hoping that the jury will agree with the charge rather than letting a proven killer go free. This may fatally backfire. If a proven killer is only charged with first degree murder, and there is insufficient evidence for first degree murder, then yes, with a responsible jury that killer will go free. If the only charge requires proof of premeditation, and there is no proof, then that charge will not succeed.
Ah, but destroying the insulin is not "tantamount to to murdering the victim". Any pharmacy or hospital can supply more. Once the villain is secured, or the cop and victim are away from the villain, additional supplies can be obtained. That does not justify deadly force. (And since the T J Hooker series was set in a large US city, such supplies would have been readily available, 24/7. If the setting was far away from any such supplies, the case would be different.) However, if the cop has plausible reason to fear that the villain will attack him or the victim, and pose a serious threat of injury or death, the cop can use as much force as is reasonably required to defend himself or the victim, including deadly force if that is needed. He may not use more force than is reasonably required, but in practice once it is established that there was a valid threat, or reasonable grounds to believe that there was a threat, the cop's judgement on how much force was needed will only be overruled in a really egregious case. Under current law, the cop may not use deadly force simply to stop the suspect from escaping, unless there is some unusual factor involved. I think the law may have been interpreted differently on that point when the TV show was made, in the early 1980s.
Yes More exactly, nations will not regard places outside of their physical limits as outside of their jurisdictions. Overview Traditionally, a nation has regarded any ship flying its flag as under its jurisdiction, and a place where it may enforce its laws. More recently, many nations will undertake to enforce laws in cases where their citizens are the victims, or in some cases the perpetrators of crimes even within other nations, and more freely on the high seas outside the physical limits or territorial waters of any country. Historically, all nations undertook to enforce laws against piracy wherever they might be committed. Several countries, including the UK and the US, now treat the UN Law of the Sea convention as part of their national law, which defines as piracy: &quot;illegal acts of violence or detention ... against persons or property on board such ship or aircraft&quot; This would include the situation described in the question. Therefore such actions could and quite likely would be prosecuted by any of several countries, depending on the registry of the vessel and the nationalities of those involved. Sources 18 U.S. Code § 7 provides that: The term “special maritime and territorial jurisdiction of the United States”, as used in this title, includes: (1) The high seas, any other waters within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State, and any vessel belonging in whole or in part to the United States or any citizen thereof, or to any corporation created by or under the laws of the United States, or of any State, Territory, District, or possession thereof, when such vessel is within the admiralty and maritime jurisdiction of the United States and out of the jurisdiction of any particular State. ... (7) Any place outside the jurisdiction of any nation with respect to an offense by or against a national of the United States. (8) To the extent permitted by international law, any foreign vessel during a voyage having a scheduled departure from or arrival in the United States with respect to an offense committed by or against a national of the United States. This US DOJ page says: Among the offenses within the special maritime and territorial jurisdiction of the United States are the crimes of murder, manslaughter, maiming, kidnapping, rape, assault, and robbery. Pursuant to 18 U.S.C. § 7(1) there is also jurisdiction over such offenses when they are committed on the high seas or any other waters within the admiralty and maritime jurisdiction of the United States that is out of the jurisdiction of any particular state. See JM 9-20.000 et seq. The page &quot;Maritime Offenses&quot; from the law offices of Trombley and Hanes says: The Federal government also exercises jurisdiction over certain maritime offenses. There is Federal jurisdiction for offenses committed on American vessels in the territorial waters, harbors and inland waterways of foreign nations. See United States v. Flores, 289 U.S. 137 (1933). ... A number of Title 18 sections specifically declare certain conduct to be a Federal crime if committed “within the special maritime and territorial jurisdiction of the United States.” See, e.g., murder, 18 U.S.C. § 1111. In some instances, the Assimilative Crimes Act, 18 U.S.C. § 13, is also applicable. See also, 15 U.S.C. § 1175; 15 U.S.C. § 1243; 16 U.S.C. § 3372. 18 U.S. Code § 1111 (b) provides that: (b) Within the special maritime and territorial jurisdiction of the United States, Whoever is guilty of murder in the first degree shall be punished by death or by imprisonment for life; Whoever is guilty of murder in the second degree, shall be imprisoned for any term of years or for life. The Britannica Article on &quot;Piracy&quot; says: Because piracy has been regarded as an offense against the law of nations, the public vessels of any state have been permitted to seize a pirate ship, to bring it into port, to try the crew (regardless of their nationality or domicile), and, if they are found guilty, to punish them and to confiscate the ship. The UN page on Piracy says: The 1982 United Nations Convention on the Law of the Sea (UNCLOS) provides the framework for the repression of piracy under international law, in particular in its articles 100 to 107 and 110. The Security Council has repeatedly reaffirmed “that international law, as reflected in the United Nations Convention on the Law of the Sea of 10 December 1982 (‘The Convention’), sets out the legal framework applicable to combating piracy and armed robbery at sea, as well as other ocean activities” (Security Council resolution 1897 (2009), adopted on 30 November 2009). Article 100 of UNCLOS provides that “[a]ll States shall cooperate to the fullest possible extent in the repression of piracy on the high seas or in any other place outside the jurisdiction of any State.” The General Assembly has also repeatedly encouraged States to cooperate to address piracy and armed robbery at sea in its resolutions on oceans and the law of the sea. For example, in its resolution 64/71 of 4 December 2009, the General Assembly recognized “the crucial role of international cooperation at the global, regional, subregional and bilateral levels in combating, in accordance with international law, threats to maritime security, including piracy”. The UK Piracy Act of 1837 defined as a crime: Whosoever, with intent to commit or at the time of or immediately before or immediately after committing the crime of piracy in respect of any ship or vessel, shall assault, with intent to murder, any person being on board of or belonging to such ship or vessel, or shall stab, cut, or wound any such person, or unlawfully do any act by which the life of such person may be endangered, shall be guilty of felony... The more modern UK law, the Merchant Shipping and Maritime Security Act of 1997 embodies the UN law of the Sea convention, including its article 101, which says: Piracy consists of any of the following acts: (a) any illegal acts of violence or detention, or any act of depredation, committed for private ends by the crew or the passengers of a private ship or a private aircraft, and directed— (a) (i) on the high seas, against another ship or aircraft, or against persons or property on board such ship or aircraft; (a) (ii) against a ship, aircraft, persons or property in a place outside the jurisdiction of any State;
