Poor people can't be diabetic?
I never said that. But anyone in their right mind, diabetic or not, would not leave a syringe on a bus which goes through Camden. Some reasons:
a) If they were diabetic, they probably do heroin too, so save a needle.
b) If they weren't diabetic, they probably did heroin.
c) If they weren't diabetic and weren't a heroin user, they were a dealer, and leaving merchandise is a no-no
