One of my closest buddies is a police detective that works a very violent area. He constantly tells people that they have to be crazy to leave their house without being armed.
Lots of LE would tell you that--off the record. I'm referring to spokesmen who appear on tv and advise people how to prevent crime.
That's the point. City and Police higher ups know you're better off armed. But it's politically incorrect to tell the public that.
