It's not a matter of every cop who is involved in an incident being convicted. It's a question of actually having a chance at justice, rather than each instance being hidden away, internally "investigated" then swept under the rug. That's why there was a big to do about seeing an incident report (of the fatal shooting, and not of a supposed theft). How many uncelebrated cases even have reports written and released? The disturbing thing is that we don't even know because fatalities
aren't consistently tallied. That's why there's a protest. If you don't make a big stink, it's business as usual until the next dead black man.
And if deaths aren't always brought to light, what about lesser incidents and aggressions like the guy tasered for hanging out near the bank (where the police said they "used the force necessary") or the elbowing above? No chance they are addressed. Especially if it is a cop's word against yours. White America believes the cops (and
supports the cops, and
makes a point of letting it be known that's the case). Unless of course there is video evidence of what went down (witnesses aren't enough, as we're seeing in Ferguson - too easy to dismiss and discredit them). And even then, the deck is stacked in the favor of the authorities.
