Dude, wtf? Are u serious? This guy did nothing wrong. He's a journalist and it seems like you don't get the idea of freedom of speech. Maybe it's because of people like you that the Russian government can do whatever it wants.
While he was working as an advisor for Kirov district governer, he supposedly forced contracts with disadvantageus prices on state owned company with a total of 16 mln rur (roughly 500k usd).
I didn't read court documents, but I wouldn't be surprised if he actually did.
Fact that he blogged about corruption for a few years doesn't make him innocent, but government probably would never looked into it if he'd keep quiet.
