I don’t really believe that.
Single officers who arrive at the scene of a mass shooting in a large building DO NOT rush the building.
Further, officers arriving at the scene of a mass shooting have long rifles of some sort, vests, and other officers on scene in seconds. Then they go in.
Even swat team member enter the facility with as a group with a highly organized method of attack.
Too many posts for me to read them all. Just one question. Has anyone gotten around to suggesting Peterson should have shot the gun out of Cruz’s hand? Maybe from around the corner, using a bank shot off the fire extinguisher?
More cores from that particular rifle ammo will blow through an attacker and hit bystanders. A pistol is far better for use inside a building. That still stands, if the attacker is wearing body armor (first hitting round buys at least a fraction of a second).
Those rifles are pretty fashion accessories, though. So tacticool.
