what? active shooter? the "Shooter" is DEAD! so yea there is no longer an active shooter but that doesnt mean there were others nearby which is why the area was evacuated. standard operating procedure. im sure ammo cooked off and shot 4 firefighters.??? are you even hearing urself as you type?
a bullet will only travel with velocity when it is in the chamber of a firearm. the brass is merely a gasket and will blow to pieces in a fire before even the slightest amount of pressure is built to launch the projectile. your a gun guy arent you? you dont know this?
its just another whacko with a gun killing people.
