Oh don't be naive. There were and still are plenty of protests in Europe. Maybe watch a programme or ten where the banlieues of Paris burned for days because a teenager was accidentally killed by the police. And the protests in the UK, where the reasons were many (racism, austerity, corruption).
Europeans saying, "this could never happen here," is as daft as an American saying it.
The keyword is "accidentally killed". But whatever suits your agenda for downplaying what's happening in the US.
"And the protests in the UK, where the reasons were many (racism, austerity, corruption)." - Absolutely not comparable to what is happening in the US. The UK had riots few years back and absolutely no leader issued statements that they will get shot, and hounds released on them. It was a big deal even whey they wanted to use water cannons. But hey, what do we European communists know.
