Unfortunately the infamous bank robbery in North Hollywood California forever changed law enforcement where they were massively out gunned. Thus they had to equip for potential further events.
I'm sorry, but I take a middle of the road approach with racism until proven, and in the cases where it does happen, it comes from all races. Not just in law enforcement, but everywhere it can happen. Racism sucks, but apparently some people haven't evolved beyond that point in our society.
There are officers of other skin colors out there you know too, and they would be doing the same thing. And in the face of situation of how the State Police were handling things, they're following orders from their Captain, who isn't white.
And like that lady said in that VICE video, there's good and bad cops. That's like that for people of every profession.
