Just because it is a far cry from direct violence or murder doesn't mean that it shouldn't be taken care of. You can harass folks with "minor" civil rights violations and make life hell for someone. I'd argue that being lenient on "minor" civil rights makes the violent ones more likely because of the lenience towards other ones.

If you want to be in law enforcement, don't commit civil rights violations. Period. You might not be able to right every wrong, but once a wrong comes to light, you can very well do something about it.
