If I booby-trap my home and somebody gets killed trying to break in, I (rightfully) go to prison for murder. If a politician booby-traps a border (with exceptions for situations involving war) and somebody gets killed trying to cross, they should end up behind bars too.
Luckily, ignorance of the law does not insulate those individuals from consequences if they act on their incorrect beliefs. Just wish we'd apply the same line of thinking without regard for the perpetrator's level of political influence.
