A lot of the lads on the NYPD could tell you about that hate. They see it every day in the eyes of people who've been steeped in it since birth. That is why when a squad of cops think one of them has a gun or is reaching for a gun the lead count hits half a hundred in seconds. The day you see that hate you'll never forget it. You can't. It is a matter of atavism and beyond your conscious control.
Demure white mothers with baby strollers (me) have seen it too. That's why I moved out of Philly.
I would've ended up having to kill one (justifiably), I'm afraid.
