People like you who say that kind of shit in response to calling the U.S out on civil rights abuses are ignorant and naive, I could easily find photo's and events where cops regularly attacked protesters in the U.S too.
Most of the protesters in Europe and us get beaten spend a few nights in detention and that's it.
In China , there are lots of people who protest , get arrested and they disappear.
Where is the guy that stopped that tank?
