"When a state massacres 600 demonstrators, it is not just its own citizens it murders."

"It also kills the possibility of compromise. The perpetrators mean you to understand that there can be no going back. When they kill, they are well aware that they are shedding too much blood for normal politics to kick in and allow differences to be patched up and deals made."

The killers have the swagger of gangsters. "We know," they seem to say, "that we are breaking all the basic standards of civilised behaviour. We know people will hate us until the day we die for what we have done today. But do you know what? We don't care."
