Hair standards for black cops?

My observation and I think this is racist (I do not think you are). I have seen black cops with braided hair protuding out of their hats. I have seen it with all assets of law enforcement agencies including Security. When I was a Security Officer I was told I had to cut my locks (I had beautiful long hair) but the black officer was able to keep his. My hair was always well kept (My wife was a hairdresser). It was because of his ethnicity I was TOLD. Total racial discrimination.
