But here in America we have no right to exact justice in this way. Too bad since this is the best way to fight crime there is. It's local and swift. Peer pressure so to speak.

What you say is 'true' but consider this:

Does justice or righteousness cower from threat of retribution?

If I do not recieve justice from the system, I retain the right to extract it myself and will do so REGARDLESS OF THE CONSEQUENCES.

True and heartfelt righteousness knows no intimidation and refuses to be put on a cost/benefit scale.

Does justice or righteousness cower from threat of retribution?

I believe that many times it does.
