Prayers sent, Now Get Her A Gun! (With proper training, of course) The old severely right wing pro-gun slogan comes to mind, " No One Ever Raped a .38!"
Seriously, a handgun in .38 special or 9mm loaded with frangible ammunition would work wonders in close quarters (ie dorm room distances) with Federal Hydra-shocks for out and about use, would give her a great layer of protection and peace of mind. For deterring crime, a gun in the hand is worth a hundred in the hands of the police. Please talk to her about this possibility, Wildman. Most people go through life with their head in the sand thinking, "Bad things can't happen to me, they happen to other people". WRONG! It is this denile that just perpetuates the criminal/victimization cycle. "Bad People" prey on the helpless. They are cowards who don't want to be hurt, so that is why they perpetrate their crimes on those they perceive won't fight back.
If your friend Natasha takes prudent precautions (READ: arming herself) She puts herself on an even playing field with this !#@$%&**.
Once Johnny Maggot knows that this kitten has claws (and ain't afraid to use 'em) he'll probably disappear.
Sorry about the Tirade, but as you can see, I feel very strongly about people being able to defend themselves. Around my ranch the Motto is "Repel all Boarders". I hope Natasha adopts a similar attitude.
