I have been thinking about purchasing a gun. I live in a neighborhood in Philly that is relatively safe, however, there have been a spat of burglaries and home invasions recently, and, living with 2 females in a house that, outside of locks and deadbolts, is pretty devoid of a "security", I feel as though some added "protection" couldn't hurt.
I was always opposed to guns, however, I work with a guy whose mother just got carjacked at gunpoint not too far from where I work and he has since bought a gun for him and her, which has provided him, his fiance, and his mother peace of mind.
