He was Lieutenant Colonel when he left in '91. I don't think you spend 15 years in the KGB and get to that rank without learning a thing or to about 'playing games'.

Slightly different beasts I think. R is a really impressive analysis tool. Python is a scripting language. The latter is quite a bit more versatile, but
Well, you can. You get to vote. Or move to another country. Or declare independence. I understand that's worked out well occasionally.
There's always always a balance. The police have powers to investigate the innocent. They're innocent because they're - legally - innocent until _proven_ guilty. Which means - by definition - the police are always targeting 'the innocent'. There's a bunch of rules to limit this, including not least a system of warrants - to do certain things to people, you need to be able to convince a judge that they're sufficiently dirty to be worth further investigation. But they're still - in the literal sense - still innocent at that point, because you haven't proven their crime in a court of law.
It's not a perfect system by any means, but it mostly works - _generally_ the bad people get caught and punished, and the good people are protected. But sometimes there are abuses, and part of the point of any system of justices is that it has to accept the inevitable - that sometimes you'll get it wrong.
But it's generally accepted to be one of the least bad options.
