One time while walking back from a bar in my mid 20s I ran across a street in front of a police cruiser as the light was yellow and they exerted their power by hassling me and telling my friends to watch out for me. This was Fullerton, CA and I am a short white guy with a shaved head. You may think they were watching out for me but there was significant belligerence. The point is they enforce whatever, whenever. There are far too many laws and they are very unevenly enforced.
