They do that in the GTA games. Its funny how I shoot them through the doors because they think thats actually safe.
Yep the GTA III era games the doors have no-collision which is pretty funny.
Also I'm in Delaware as a last minute vacation and I stopped by the Air force base in Dover and snapped this pic of captured Iraqi weapons, I would kill to hold these.
