What happens if the knife-wielding assailant you pull the fake gun on pulls out his gun? Just a thought.
They still haven't found the woman abducted in Conway, but they have captured her two kidnappers. I live about 50 minutes from Conway, and go through it to get to MYB rather often. Scares the crap out of me, but I don't go anywhere without at least one firearm. Even though I'm 6'6", and 240lbs, I usually carry one on my person, and one in the glovebox. I am very comfortable around them (not so comfortable that I ignore safety, though), I know when to shoot, I can hit very well, and I'm legally licensed to carry them.
That being said, I definitely don't recommend this to everybody. If you have had training in firearms safety, and the laws of your state regarding when you can legally defend yourself, and you feel comfortable carrying one, then by all means do so. However, if guns scare you, or you're not sure of your capabilities, don't think of carrying one. Buy some pepper spray, or a tazer gun, or something that you feel comfortable with. There's an extremely large personal defense industry out there that would be happy to help you out.
About two years ago, my aunt was accosted by a man with a gun in the mall parking lot. Before he even got her money, he hit her in the eye with the gun, knocking it out, and crushing her occular socket. She kicked him in the gonads, and drove herself to the ED. I've never let my sisters or wife go anywhere alone since.
