No it's not!!No disrespect, but you can't compare what happens in a warzone against enemy combatants to what the police/SWAT teams (civilians) do to other civilians. Apples and oranges, and a very telling look at the mentality of many police officers. If you want to play soldier and play with the dangerous toys, join the military. Keep that crap off our streets, which is a direct violation of Posse Comitatus.
It only is a violation if troops of The United States Military are used in Civil Police actions.
