@Renaldo Dubois,
I do believe in a justice system like most democratic countries have.
Thus, you need a trial and a verdict.
Any information got by illegal methods can't be used in trials in those democratic countries.
Someone, who uses these illegal methods ... gets accused of it.
Killing an unarmed person is either manslaughter or murder.
Their may be laws which allow this under certain circumstances.
I don't know enough about the US criminal code to make a judgement here.
But I've never hidden that I dislike such and think it to be illegal.
