I can see why it was manslaughter and not murder as it was only 1 hit and didn't have the intent. There is no doubt that the punishment needs to be harsher but as stupid as it sounds, these morons were unlucky the victim died. IMO there should be much harsher punishment on the far more common occasions when the vicitm isn't badly injured to deter attacks from happening and the infrequent death. I'm not sure prison will help them, maybe some kind of corporal punishment might be more effective. They clearly enjoy violence.
It's obviously manslaughter, but 3/4 years is nowhere near enough, 10 would be way more appropriate! And the death penalty should definately be brought back - but only for murderers who performed the crime intentionally, with malice.
It's because the guy is 67 they are hardly sentencing him, i bet if the guy was 40 he'd gt alot more.
