I agree but until the states quit taking money provided by the government which allows that government to hamstring the individual states then it is what it is. Example: Under Jimmy Carter, the states had to abide by a 55 mph mandate or suffer the consequences of the loss of Federal subsidies. The latest good example is when Biden pulled necessary medical equipment and drugs from the state of Florida in order to force the Governor into keeping certain businesses closed and masking mandates. The State of Florida bought what was necessary from another country thereby bypassing Joe Biden’s mandates.
Murder is still NOT a Federal crime except if it involves a Federal employee or contractor. Murder and rape are still left to the states to prosecute.
Federal murder jurisdiction includes more than what you list. Rape can be a federal crime if the elements are met, mostly the Interstate trigger.
Welcome to the forum, and thanks for jumping in on the discussions. By interstate trigger, do you mean if someone travels from one state to another in order to murder someone?
Or flight to avoid prosecution, but the laws against murder, etc. are still primarily state functions unless it involves a Federal employee.
Yes, under the federal system, the States possess primary authority for defining and enforcing the criminal law, see, Brecht v. Abrahamson, 507 U. S. 619. However federal murder involves other elements. If I conspire to commit murder by U.S. mail, and succeed, that triggers it. If a tourist is killed in a federal park, etc. that qualifies. It does not have to be a federal employee.
