In the UK we have had several recent cases of corperate manslaughter been bought, particularly after railway accidents.
In most of them, no one individual could be indentified as being the person whose incompetence premeditated the accident or incident, although it's obvious, that, as in this case, corporate greed was the overiding factor.
Frankly, I am amazed that none of the relatives affected by any of these other incidents, have not taken the direct action which the Russian chap did.
I don't condone his actions, clearly he was severely traumatised and probably went a lot further than he intended to, but in the same situation, who are any of us to judge him?
