Could two people be convicted for the same crime? Suppose a serious crime is committed, and there is no dispute that one person, acting alone, committed the crime without any assistance. Police wrongly believe that person (A) committed the crime. Person (A) is wrongfully convicted and sent to prison. The real perpetrator is person (B). After person (A) is already in prison, the police discover proof that person (B) committed the crime. Do the police and prosecutors have to exonerate person (A) in order to charge person (B)? (Obviously it would be incredibly unethical to charge B without exonerating A, but I'm asking whether it is legal.)
If the prosecutor (P) knows or strongly believes based on this new evidence that A is innocent, ethically P should start proceeding to have A's conviction reversed or reviewed. But in far too many cases P does nothing of the sort. If P simply files a charge against B and proceeds to try B for the crime, P leaves it open to B's Lawyer to ask &quot;Didn't you already convict A for this crime? what about that?&quot; as part of a defense, which might well embarrass P and lose the case. So P may well choose to file charges against B claiming that A &amp; B acted together as accomplices, even if this requires misstating the evidence, or suppressing part of it. Or, P may simply ignore the new evidence, leaving A in prison and B free. This is unjust, but requires no effort on the part of P, and may seem less likely to raise embarrassing questions about why P got the case against A wrong. P can always claim that s/he did not believe the new evidence. That might even be true, there is such a tendency to believe what we wish to believe. The relative frequency of these responses on the part of those in the position of P here is really not possible to asses. The last two responses involve P suppressing or at least burying relevant evidence, and unless it is brought to the attention of others who publicize it enough that action is taken, it will not be generally known and cannot be tabulated in any statistics. P's office will certainly not respond to any survey which asks &quot;How many times this year did you suppress the true facts to leave in place an unjust conviction you had previously obtained?&quot;
A problem with the question is that it uses the loaded term "victim". If you change the question to "Are there actions that you can perform involving another person, which are crimes even if the other person consents to participating in the action", then there are very many. Selling alcohol to a minor; selling heroin to anyone; selling sex in most US jurisdictions; selling firearms to a convicted felon. Also, for a physician to assist a person in suicide, in most states. Formerly in the US, various forms of sexual intercourse were acts that consent did not make legal. Whether or not the person is a "victim" in these cases is open to debate. In the case of physician-assisted suicide in Washington, the doctor is allowed to prescribe (oral) drugs that the person ingests: only a doctor is permitted to do this, both under the DWD Act and as a consequence that only a doctor can prescribe the drugs. There seems to be a belief that it is a crime to assist a person in committing suicide, which is probably correct if the assistance is shooting the person in the head, or in general directly causing the death (thus, "I give you permission to shoot me in the head" doesn't cut it). But from what I can tell, it is not generally against the law in Washington to help a person who commits suicide (e.g. supplying the means of self-dispatching). In some countries, suicide and helping with suicide is illegal, e.g. in Kenya Penal Code 225 says Any person who (a) procures another to kill himself; or (b) counsels another to kill himself and thereby induces him to do so; or (c) aids another in killing himself, is guilty of a felony and is liable to imprisonment for life. No exception is created if the person consents to being aided to kill himself.
There's no legal requirement in Canada or US that the police do anything to investigate a crime, so there's no requirement that they do anything specific to investigate a crime. If the police officers are satisfied by the witness accounts, or have some reason to think viewing surveillance recording wouldn't be useful they don't have to, either by law or policy. Note that ordinarily, police won't consider a physical altercation between two grown men a serious enough crime to warrant charges. If there was no serious injury and there wasn't a large discrepancy between the strength of the two men, police will often decline to lay charges even when they believe the evidence would sustain them. In this case the police may have decided it wasn't worth investigating further because it wasn't worth wasting the time of an already overloaded court system. The victim here still has legal options despite the lack action by the police. He can subpoena the video evidence if he wants to bring lawsuit for damages. In Canada, it's possible even to lay your own criminal charges in a private prosecution, although this much more expensive than a civil lawsuit.
You asked, &quot;could that guy as defendant claim self defense and win?&quot; First let's try to make it clear what is meant by &quot;win&quot;. In the Rittenhouse trial, the defendant was charged of the following crimes: First-degree reckless homicide First-degree recklessly endangering safety (x2) First-degree intentional homicide Attempted first-degree intentional homicide Possession of a dangerous weapon by a person under 18 (dismissed) Failure to comply with an emergency order from state or local government (dismissed) Rather than thinking of the defendant as a &quot;winner&quot;, it might be more appropriate to say that he was &quot;acquitted&quot; of these charges. If someone that was involved in the conflict fired first, as you described here: &quot;They encounter each other when each is leaning or reaching or tripping, or whatever it would take for them to unintentionally point their gun at your head. You react and you raise your gun in defense, he spots your move and points his at you. You both fire. You shoot each other and you both are gravely injured. Like, paralyzed&quot;, then would they also be acquitted of all of the non-dismissed charges listed above? If everything was as you described (&quot;unintentional&quot;, &quot;reactionary&quot;, and &quot;in defense&quot;), then likely they would also not be found guilty of those crimes. It's not like they would &quot;win&quot;, it's more like they will not be found guilty of committing one of those crimes. The precise outcome will depend on all the facts involved in the case, and the jury's decision based on those facts. So there is no single answer that always applies to every situation, but it sounds like you're wondering about some hypothetical situation that appears to be paradoxical because in this case only one person was charged with crimes: if someone else was the first shooter, the sequence of following events would first of all depend on whether or not they got charged with a crime, and I wouldn't characterize the outcome as a &quot;win&quot; or &quot;lose&quot; but as an &quot;acquittal&quot; or &quot;conviction&quot;, and yes it is possible to be acquitted if everything is &quot;accidental&quot; as you described, and presumably not &quot;reckless&quot; (often meaning that a reasonable person in the same situation would have done the same thing). About your more broad question: &quot;Is mutual self defense a thing?&quot; It depends on what crime is being charged against the defendant. In the Rittenhouse case there was only one person that was charged. If you're asking about a hypothetical situation in which two people involved in a 1-on-1 conflict both claim self-defense, I hope I can assume that they were both charged with a crime against which to defend themselves in court in the first place. It is indeed possible for a State to prosecute both parties of a 1-on-1 physical conflict, and for both of them to successfully claim self-defense in order to eventually be both acquitted. It wouldn't be called &quot;mutual self-defense&quot;, but each defendant would make their own self-defense case individually.
Double jeopardy applies to the same facts, not to the same sorts of crimes. Say if you are tried and acquitted of murder of person A, that won't later save you from being tried for murder of person B. Same applies to your question: if the documents/testimony on the second occasion are different from the first occasion, there is no protection. If they are the same, there is.
If the victim is unable to prove who the culprit was, then it will be impossible to prosecute that person criminally or sue them for civil damages. Incidents like these are rarely enough to cause a police department to throw sufficient investigative resources at it to crack the case without some reason to believe that it is part of something bigger. An unfortunate fact of life is that most perpetrators of crimes and torts get away with it and are not caught. And, if the only available witness is willing to lie to cover up the name of the guilty party (probably out of a desire to not have the dog put down), it is that much harder. A private investigator might be able to solve the case, but the cost of hiring a PI would probably exceed the benefit that could be obtained if the PI was successful.
The defence sees the prosecution evidence; witnesses don’t From context, it appears that Ms. DeCoutere was a prosecution witness, not the defendant. As such, she would not be privy to the evidence that either the prosecution or defence had or intended to present. No doubt both the prosecution and the defence would have known about the photograph and, I would imagine, it was introduced by the defence precisely because it contradicted the witness’ testimony. Further, revealing such evidence to her by either side would be misconduct - witnesses are supposed to recount the facts as they recall them without prompting or aide memoirs (police are an exception - they are allowed to refer to their own notebooks).
Yes, a crime is committed as is a tort. The exact crime would vary from state to state. The most common description of this crime and tort would be &quot;fraud&quot; but the way that criminal conduct is allocated between particular offenses in states varies considerable. Theft (in jurisdictions where it is broadly defined) and shoplifting (in jurisdictions where it is a distinct offense) would be two other plausible offenses.
