Twice;  1- not wound up pointed AT me, but the cop car slammed the breaks where I was about to cross, came around the car, pulled out the gun and started aiming.  My hands were already up when I realized it was some crack dealer (he looked the part) on a pay phone about 5-10ft from me.  Carried onto work, however, the white crackhead criminal surrendered immediately got into felony prone before it was demanded.  Like he had done that dance before.  I got off at a train station that was near a place where people buy meth, it had a sub shop next and for whatever reason "food" = meth.  So, guy asks me "you hungry, want some food" I reply trolling, "fuck ya, I'm getting a sandwich".  Cop appears, "you 3 up against the wall", I look at the cop, "who me?" I laugh and comply, he only had his gun out for a second, spent about 15 minutes digging through the meth heads pockets and asking if I knew what it was, I flapped my pockets for him, that made him nervous. But after laughing about how I would never touch meth and just looking at the scum I knew it was probably meth stuff.   It's always funnier dealing with cops after establishing that you're not going to be arrested in any way (or ticketed)
