R.I.P to the man...regardless of his faults. He is no longer here to defend himself, so we need not go off on what he did wrong in life...but rather what he did that was positive.
And just an FYI, I think that "accident" was a fucked off situation, and the dude should have done serious time for it...but that's not the point here...the man is dead...pay your respects or don't, but there's no need to bash the man.
