Please elaborate on what criminal actions BP committed.
(Hint: there are none and no such charges will be brought)
Well, willful, wanton negligence can be considered criminal.
If you know a public bridge is going to collapse and put people's lives at risk, and you have the ability to fix it or inform the people responsible for fixing it, and you don't, just because you don't give a shit; that's criminal.
However, BP hasn't been proven guilty of that yet. So I'm not pointing any fingers.
