It's not clear to me why "Policing is dangerous" means things like strangling handcuffed prisoners, raping detainees, attacking journalists and peaceful protestors, and stealing cash and other valuables (i.e. civil forfeiture) and so on have to be tolerated. None of these are "split second life or death decisions".
Just as crimes against police are more serious than crimes against civilians (rightly, IMO), crimes by police should also be more serious.
