I'm sorry but the "evidence" that leftists have presented to me so far to "prove" that there's institutionalized racism in the US is a complete joke. After crying wolf so many times I'm very unlikely to ever take them seriously even if they do come up with genuine evidence.
First it was the whole Brown shooting. Despite the fact that there was ZERO, absolutely ZERO evidence of racism or even police misconduct, they still made a big deal about it and when the courts finally said "You're wrong" instead of giving up they saw this as evidence of RAMPANT RACISM in the court rooms because you know everyone involved, the judge, grand jury with 3 blacks in it AND even the prosecutor ALL are evil racists who hate black men for being black. All this was is one jock with delusions of grandeur resisting arrest and getting his ass handed to him. If he had surrendered peacefully he'd still be alive.
Then it was the Garner case. Nevermind that he too resisted arrested and we got it on tape and there's NO evidence of racism there either. Maybe instead of blaming police there's some responsibility on his part. DON'T RESIST ARREST, especially if you know you have a bad heart and are in poor physical condition. Shit can and will happen.
Oh and for those claiming that the police were excessively violent in trying to restrain him in this case and this only happens to blacks, wrong again:

Personally I don't blame the police given the kind of violence they have to deal with. Better that they use slightly more force and live than risk getting overpowered by thugs and criminals and end up in a body bag.
Finally you had the case with the black college student (son of some journalist or whatever) mistaken for a thief because they looked alike, so a cop stopped him at gunpoint though didn't shoot. This was presented as a case of racial profiling and racism, even though it turned out that the cop was also black. What a joke.
I'm sorry but if this is the best you can offer then I can say with absolute confidence that whatever racism still exists in the US it's rare, it's dying and it's dying fast. Democrats do not like this because it means they lose votes. Activists do not like this because it means they lose their careers as professional agitators.
