Believe me, I moved! But I lived for several years on the edge of South Philly, there were projects nearby and all the college kids walking around at night were easy targets.
Once I was mugged at knifepoint at an ATM in a vestibule that required an ATM card to enter. At the police station, a friend of mine walked in. Turned out, he'd been mugged moments earlier by the same guy, who took his wallet. Thus, it was my friend's ATM card used by the mugger to get to me. I was young and being stupid, because I wanted to get money to buy a subway pass that night, instead of dealing with it in the morning when it would've been safer.
The last time I was mugged, I ignored my intuition which was telling me to cross the street. I told myself I was being racist. Moments later, I was on the wrong end of a handgun.
Since I left Philly (years ago) I've never had any trouble. Getting mugged sucks.
