It seems like a problem of states trying to pass laws that control things outside their borders. The jurisdiction of Louisiana courts is Louisiana.
I mean it would be absurd if an anti-death-sentence state started trying to extradite the executioners working in pro-death-sentence states for murder, right?
If the executioner did their work in the anti-death-sentence state it wouldn't seem to be absurd, no. E. g. if they had pulled the cord that activated the electric chair remotely from a pro-death-sentence state (tele-execution ... sounds very BlackMirror).
"The Zone of Death is the 50-square-mile (130 km2) area in the Idaho section of Yellowstone National Park in which, as a result of the Vicinage Clause in the Constitution of the United States, a person may be able to theoretically avoid conviction for any major crime, up to and including murder"
That's a separate thing -- it's not about being in a different state from where the crime was committed, it's about (supposedly) it being procedurally impossible to give you the jury trial you have to have, because literally no one lives in the relevant district.
Which really just means of anyone tried to exploit the loophole and wasn’t politically untouchable cough, everyone would just ignore the problem and assign them to some nearby district or whatever.
No, because no one lives in the relevant combination of state and district, hence why only portion of the District of Wyoming that is actually in the State of Idaho is affected.
Not by the same definition, no, its not, though there is a crime called "murder" in all states, and there tends to be significant overlap in the definitions.
Even if there aren't (there are cases where individuals fight extradition to other states though I have no idea if that's ever effective, and questions of conflict between states has come up recently regarding interstate prescribing of abortion medications, etc. with some states explicitly stating that they will not cooperate with Texasistan), a civil judgement against an entity operating in one state could likely be enforced without even interacting with the state where that entity exists - e.g. if they're using a bank with a presence in MS, the state might be able to simply go after their accounts held with the national-scale bank.
It would be pretty crazy if you could kill someone in Arizona and then just walk over the border to California and not be able to be prosecuted…
