Beating someone to death.
An honest mistake.
I'll accept that in situations like this policemen/women shouldn't be judged on the same standards as ordinary civilians. But the fact this bloke has got off free is laughable. Considering his history, he shouldn't even have been there in the first place. Sounds like a thug in a uniform.
There have been 1,500 deaths in police custody in the uk.
Number of police convicted of murder or manslaughter: 0.
Nothing to see here. Move on.
