TV shows crack me up. Love it when people hide behind walls, doors, appliances etc and are magically safe from bullets. I've shot enough at the dump to know otherwise.
The only thing in my house that I think might stop a handgun round would be my old cast iron bath tub (but I'm not going to test that theory), I don't think anything in the house would stop a rifle round on it's own.
I would question whether the engine block on some of these newer cars would even stop a rifle round unless it hit dead center.
Hollywood is and has been the worst teacher of firearm physics and history, but people who have never experienced otherwise eat it up like it's gospel.
