>> Or: Broken tail-light -> hiding face behind hoodie -> hmm's and haw's when asked to leave vehicle for DUI test -> acting aggressive -> etc.

And a last objection: that's a crap (sorry) way to profile people. A kid with a hoodie talking trash to a cop is most probably a teenager trying to grow up -and failing, currently. Give them the time to succeed and go bust someone actually doing some harm. Everyone 'll be the better off in a world with more adults than juvenile idiots.

How often do you guess real perps go looking for trouble with the police? I'd guess, not very.
