You would have tags for that deer or you would be a poacher. Your argument is a non sequitur. Deer aren't American citizens.
We already knew Al Awlaki was a problem long before we located him. There was plenty of time to obtain a warrant. If you haven't got anything better than that, you don't have anything.
I'd shoot him and any other Al Qaeda planner without batting an eye, legal or not. He could be Arnold Schwarzeneggar's lovechild, and wrapping himself in the Red, White, and Blue, but if he was an Al Qaeda planner, I'd pull the trigger first and shed crocodile tears later.
Go the "Al Awlaki Killed" threads from last year(?) and see how many were grieving.
People on here are acting like this government has never run a hit on anyone in the past. That's crazy.
