Definitely. It is sad that the police as a whole have a bad rep because of a few bad apples.
I'm indifferent to black lives matter not because I think they're giving out the wrong message (I get what they're trying to say), but I feel like lately it's gone more from protesting to rioting (destroying property, harrasing other folks, etc).
I respect cops that follow the law and do what they have to do if the suspect isn't cooperating. I don't like the ones who, as you said, abuse their powers, and I feel like I always hear this with NY cops, Baltimore cops, Chicago cops, etc.
