Okay, maybe it is racially motivated. However, we shouldn't automatically assume that just because he happens to be black. I, personally, am inclined to believe it is a racist incident. On the other hand, I don't know enough of the details to assume so.
Okay, then where's all the white kids in jail for things they didn't do?
The converse is "where are all the other black kids in jail for things they didn't do?"
And, of course, NYPD being the scumbag force it is won't tell us. I mean, the minute we know the number is the minute those people are released. So, this question isn't the best way to make that point. Instead, it would be better to say that the NYPD has a long history of racism and abuse of power and (surprise-surprise) the victim here is black.
I mean, the link I provided shows it best, a white guy of affluence acts suspicious trying to attract attention and gets none. He then spray paints a public building within sight of officers. Finally, he turned himself in and was let go because the police didn't believe he would do it.
I mean, after reading this story, I realize the NYPD is a two headed monster. One is tyrannical and domineering, harassing you at every possible moment if you're not a cis-straight-white person. Stop and frisk, beat downs, using gender identity as probable cause for charges. The other head is fucking stupid. It's a bumbling and inept officer Barbrady incarnate. It couldn't find weed on you if you blew pot smoke in its face. But of course, only if you're white.
TL;DR- Fight the power
