Earlier quoted context omitted.
Are you exaggerating or are you seriously concerned that the police will harm you? No matter what your race/gender/color/face/etc., citizens are far more dangerous. There's simply tons of them. Even in the US, this whole police-violence thing is a bit of a red herring. Yes, it's terrible, police need to be checked more, etc. But no, it's not a "massacre" or remotely the top reason someone will be killed.
If I am assaulted and mugged I get some bruises and lose my wallet. Those are relatively minor outcomes compared to the enormous court expenses and years or a lifetime of damage that an officer can do. Hell, as per the article, the $300 to get my car out of impound would be a lot more than the pocket change I stand to lose in a mugging. Most well-fed sharks won't attack a human, but I'm not about to dive into the tan…
I don't think you're actually calculating the risk here.
