Why are the police so vindictive to religious minorities, i have recently been handcuffed and thrown in a cell?

for practically nothing, yet a rich banker gets off with daylight robbery. All I did was hit a couple of guys with a scaffolding pipe for looking at my wife and i get demonized, isn't it true.......one rule for the rich and another for the poor and if you happen to be from a religious minority another yet still.
