I've always found those colors less obvious in video at least. I suppose in real life it would be different. I grew up around Seattle PD and didn't get why cop cars were called black and whites until I was older though.

I remember reading a book written by a cop that was pretty brutally honest. He admitted to being racist, but there was a story about a little kid getting hurt. At the end of it he said he didn't talk about the race of the kid. Because as racist as cops can be, they aren't about a kid. He also said it would tarnish the average persons reading of the story. That story really messed with me.

Hate cops all you want. Every one I've known is super protective of kids.
