Don't feel bad. When I started reading this, I thought it was about St. Petersburg, Russia also.
I thought it was about Russia because I couldn't believe an article about black on white hate crimes was appearing in a US paper!
I guess riots can be expected any time police kill a black suspect, no matter how deadly or how much of a threat he is.
Wasn't there some racial violence in 1996 in St Pete, shortly after the vice presidential debate was held there? As I recall it was the same kind of thing. White motorists were assaulted and their cars were pelted.
