"I have an obvious thing to say: you are not allowed to give up! If they decide to kill me, it means we are incredibly strong. We need to use this power to not give up, to remember that we have great power being oppressed by those bad guys. We don't realize how strong we are.

The only thing necessary for evil to triumph is for good people to do nothing. So, don't stand still."

Alexei Navalny, 47, opponent of Vladimir Putin, who died today in a Russian prison in Siberia.
