Once I was in Belarus. It's a heavily authoritarian country, make no mistake. When they had protests against their rigged elections, they traced the phones of everyone who went, then brought them in for questioning and asked them what they were doing there. The president later said: "We have rigged the latest election. 93.5 per cent have voted for Lukashenko. But they say it is not a European outcome. We have made it 86 per cent."
But it does work. I was at a restaurant there. Some girls are chatting, and they walk away to go get something, and just leave their bags there unattended. Why? Because it's an authoritarian country - people aren't going to steal stuff there.
This was in the capital of one of the poorest countries in Europe, but it was still one of the safest places I've ever been.
EDIT: I don't mean to praise authoritarian countries, on the contrary. We should support human rights even if it is less efficient, because the object of governance is not to strip people of their freedoms for pennies on the dollar.
