A good shot
In Torrance, CA. Rapist chokes woman from behind, she gets out a .22 (the .22 you have has more stopping power than the .45 you left at home) and fires two shots over her shoulder. One was a solid hit, and the rapist expires. DNA shows he also committed a murder back in the 90s.
"A few weeks after Kemp died, Torrance's city prosecutor said the woman who shot him might have been illegally carrying the gun in her purse, but cleared her of wrongdoing in the interest of justice."
So much for the remark of Colorado State Senator Evie Hudak, to a rape victim: "Chances are that if you had had a gun, then he would have been able to get that from you and possibly use it against you."
