It's not that easy when a cop is harassing you, and you haven't done anything wrong.
Absolutely true.
On top of that, you know he wouldn't be doing it if you were white.
Police in some places do seem to harass young men (or people who look like they don't belong in the area) regardless of their race. I have an old friend who's a cop, I don't see him much anymore, but when I listen to him and his cop buddies, I think I hope I never get pulled over by cops like them.
