I'm sure you'll all be pleased that I'm not going to comment any further on my personal opinion - which is I suspect, as H Jones say's, principally down to something of a minor clash of cultural assumptions. But I thought this article interesting, due specifically to the comment at the end. It appears the neighbourhood is a predominately Latino area, and a white guy who doesn't "fit in" was the major issue. Cut and paste comment:

The police always do this — "stop" a white guy in a "high crime area" or whatever the convenient pretext might be. If a white guy is out of place, they assume he's there to buy drugs."

I do not know if this is a correct statement, but I found it interesting in light of Azizi's prior comments. Look Out Kid, It's Something You Did: Bob Dylan Stopped By Police, Asked For I.D
