unfortunatly they will probably have charged him with manslaughter due to there being no premeditated actions leading up to the attack
and, the judge should have also been thinking about the victims family, it seems that "justice" is biased towards the defendant and their incarcerations affects on their families, rather than being fairly weighted towards the victims who's families and friends aren't considered in the sentancing
if his 2 kids didn't have a nasty cunt of a father, then they'd be able to spend more time with him, hardly their fault but it would probably have done them more favours him not being in their lives if this is what he is going to be bringing to their education
