I agree with Kelsey. You gun nuts crack me up.
What city are you talking about anyway?
Odds are she will never need it, and the odds that she will are about the same as those of it being used against her --attacked from behind, by a gang etc.
Not to mention if someone pulls a gun on her , she's more likely to get shot if shes tries to pull hers, than if she hands over the money -- and same deal in a sexual assault.
It's a lot safer just to use common sense.
I live in New York an have for 15 years and have never been in a situation where I needed a gun for self defence, nor do I know anybody else male or female who has.
Attackers don't act like sitting ducks on a pistol range
Ps A .357 LOL!
PPS Dude, you may think you NEED a gun. I don't NEED one
and I really don't think a grad student needs one. Some people need guns -- cops and people who carry a lot of cash, work in jewerly stores etc. And surely you understand the gun is a last resort?
Also, FYI here's how a typical Urban University deals with safety issues. http://www.columbia.edu/cu/facets/0708_safety.pdf
