How illegal is drug planting? Let's say you leave fake drugs in someone's yard. Eg, you expect the police to be dumb enough to believe it and arrest the other person, but if caught, you can show they are obviously fake. What crimes have I committed? Is it just trespassing? Isnt there any crime for planting fake evidence?
Let's say you leave fake drugs in someone's yard. Eg, you expect the police to be dumb enough to believe it and arrest the other person Obstructing a public officer, specifically "deliberately hindering a public officer from carrying out official duties". Trespassing.
can an individual be charged with selling an illegal substance if they are not in possession or received money for an illegal substance Yes. Testimonies, affidavits, receipts, fingerprints, and circumstantial evidence might conclusively establish that the individual engaged in illegal activity.
The 5th amendment protects you from self-incrimination. If by possessing a firearm you are in violation of the law you cannot be compelled by law to reveal this information. If the police discover you have a gun in violation of the law you can be arrested and prosecuted for that offense. They cannot additionally prosecute you for not telling them about a gun. I thought there was a supreme court case about this specific situation, but the closest I can find for now is Haynes v. United States. The 7-1 majority held that people prohibited from possessing firearms cannot be compelled to register their firearms that they are possessing illegally. They are stopped by the police and asked this question. They answer truthfully. Then they can be arrested and prosecuted for the illegal possession of the gun. How does this square with the right not to self-incriminate? Or is asking the question considered to be a search? Police can generally ask whatever they want. If you choose to waive your 5th amendment rights, that's your mistake. Can the state prosecute this person for carrying the illegal weapon? The state can generally prosecute crimes it knows about. So yes, in this case they can. Suppose that next to the weapon a stash of illegal drugs is discovered, which was only found due to the action taken to secure the weapon. Can the state prosecute for that? The state can generally prosecute additional crimes it uncovers during investigations or other lawful actions. So yes, this can be prosecuted.
A person cannot be arrested for a misdemeanor by a police officer without a warrant unless the officer has probable cause that a person committed a misdemeanor in their presence. "Probable cause" is when the facts objectively support a belief that the person has committed a crime. If there is a total lack of evidence, then there is no probable cause or even reasonable suspicion, so an arrest (for anything) when there is absolutely no evidence that the person committed a crime would be illegal. If, for example, an officer decides he hates your face and arrests you for littering without any reason whatsoever, that would be illegal and a cause for a lawsuit. An officer might arrest a person for smoking marijuana in public based on a person exuding the smell of marijuana and seeing the person smoking a hand-rolled cigarette, but they could also be factually mistaken as to whether the person had actually been smoking marijuana at the time: perhaps they were wearing marijuana-smelling perfume and were smoking a regular tobacco cigarette. The evidence for the crime would not be completely non-existent, but would be insufficient for a conviction. If the officer failed to take the cigarette as evidence, that would be a problem, because the remaining evidence (visual and olfactory) would not support a conviction.
Under U.S. law the prosecution must prove that the defendant committed a particular crime beyond a reasonable doubt. So, it is not sufficient to prove that someone committed one of three crimes without proving which one it was. an alternative that I thought of later: someone is found somewhere where they can legally be, but in a situation where the only way they could have gotten there would involve trespassing through one of several properties owned by different people. Since the crime of trespassing requires the prosecution merely to show that someone was on the property of another without legal authorization to do so, it might be possible to prove this crime beyond a reasonable doubt without showing precisely which property was crossed, although I wouldn't be surprised if there was a split of authority among U.S. states on this question.
There are two issues, one is the legal issue of whether what you are doing is a crime, and the other is the evidentiary issue of proving that that is what happened. If you take the phone home with the intention of keeping it ('finders keepers') then you have committed larceny (sometimes called 'theft', sometimes correctly). This specific type is called 'larceny by finding'. If you take the phone home with the intention of finding the owner then you have not committed larceny because you have not committed the mental element ('mens rea') of the offence: you don't intend to permanently deprive the owner of their rights. However, and this is the evidentiary issue, if hypothetically you were found in possession of the phone then the police might not believe your explanation and a court might well convict you of larceny. P.S. Firefox has marked 'evidentiary' as a spelling error and suggested 'penitentiary' instead. :s
Charged? Of course, the police can charge you with anything at any time Could you be convicted? Maybe. Their best shot is charging you with “Manslaughter by an unlawful and dangerous act” also called constructive manslaughter. The Crown must prove your act: was intentional, was unlawful, leads the reasonable person to realise that some other person is at risk of physical harm, and caused the death. The first two are uncontestable: the protesters are deliberately engaging in an illegal act. No 3 would be up to the jury. No 4 is also up to the jury and would turn on the evidence that the delay to the ambulance caused the death.
When a country makes criminal laws, these laws usually apply to anyone present in the country, and acting in the country. But the country is free to declare that some law might apply to its own citizens in a foreign country, or even foreign citizens in a foreign country. Assuming the laws about using marijuana say nothing about the country, that most likely means it only applies to using marjuana in the country itself. But if the US government decided that taking marijuana in Canada is illegal for US citizens, then nobody can stop them. In this case, Canada would not extradite you (unless Canadian law says that it is criminal for Canadians to use marijuana in another country), and Canadian police would likely not collect evidence. So even if illegal, it would be hard to convict you. PS. The "polygamy" case would be interesting, I think you would have to read the exact wording of the laws in every country. Some countries will say that you can't get married twice, and the attempt to get married a second time while already married is bigamy. In that kind of country you wouldn't have committed a crime within that country. Also, you would only be married to the first wife.
