Well, Shippensburg PA didn't have one when a headcase went into their local Kmart, asked to see a shotgun, then loaded it and took the whole store hostage. It took the State Police quite a while to get their Emergency Response team in position...and the first thing all the monday morning quarterbacks were asking was why the Shippensburg PD (which actually didn't have jurisdiction...it was just outside of town, but nevermind that) didn't have a 'SWAT' team. *roll eyes*
I mean, chances are you'll never be attacked. you don't really need your guns, either.
