Would you accept other countries blowing up Americans because some Americans bring drugs and other things into other countries?
Assumes facts not in evidence.
Also, there's great reasons to have punishments for crimes that are not just summary executions. Even if you have a warped morality where all criminals of any sort should die, there's _still_ great reasons to not allow that to be chosen by the closest person with a gun. That way lies chaos and corruption.
If youre implying the people being killed are innocent countrymen of the real criminals then of course I object. Everything I have said applies to people actually comitting crimes
Seems rather incompatible with a justice system, and hard to distinguish from random military action.
