If he walked near a window with his weapon and a sniper put a .308 in his head would you feel any differently? That certainly would have been justified as he had shown himself to be a direct threat to the officers on the scene. Don't get me wrong, I am not real comfortable with burning a building down like that, but when I asked myself the above question it did make me thing some.
I came to the conclusion I am not real thrilled with how the situation was handled, but I understand why it went down that way. The policy and procedure should probably be changed...if there is one in place.
