Well if a lunatic was spraying a neighbourhood with machine gun fire and a cop inadvertently struck a bystander in trying to take down the gunman, I would empathise with the cop, and definitely not the lunatic gunman.
But Putin bum-lickers have strange ideas and would no doubt argue - the lunatic gunman was provoked by the expansion of the local police force - support for the police is part of a nefarious money laundering scheme - police weapons may get sold on the black market to terrorists - the cop was possibly affiliated with Soros and the WEF - the lunatic gunman was fighting Paganism and Satanism - the entire shooting was a false flag
