It's not a little OT. It is way OT. Mentioning the words self-defense (in a contrived way) does not bring it any closer to being about open carry.
You are right on the cop-bashing. I was wrong. I am sorry. The reference was not even directed at your post. However, I was still wrong and have edited the assertion out of my post.
Due process is a law enforcement concept. We are not sending the cops after this guy. When one makes war on the US, even if one is a citizen, he should expect the response to be a war-like response, not a law enforcement response.
If we find him, I hope we capture him and hold him until we no longer are at war with terrorists. And, make no mistake, we are at war with terrorists. Even if we decide we are not, they long ago decided we are.
However, rather than risk the smallest injury to an American trying to effect this terrorist's capture (not arrest), he should be killed at the slightest sign of resistance. Cops don't do it that way, but, again, this is not a law enforcement situation.
