other way round. cops kill people all the time - and dogs fencedin back yards, one of which my city attorney uncle had, the cop was on the other sideof the fence, looked over the fence andshot my uncles dog - so why shouldn’t regular citizens have the same ability? cops kill people defending their house from being raided by cops who dont identify themselves as cops and ever get into trouble evenif its the wrong address.
Those trigger happy dog murdering cops are quite disgusting and unfit for service.
As for this case, tragic. But I’d be loathe to charge the man with a crime.
