The employee should be given a bounty from the city or county - like about $25k.
Saved the area the costs of a trial, avoided costs of hospitalization, costs of housing this thug in prison, parole costs, costs of all the future crimes the thug would have committed. $25k is seems like a modest thank you given the NPV of all the costs he saved taxpayers.
NPV has to be in the millions of dollars. And that’s before putting any value on the incalculable mental anguish of victims. Crime victims take years to get over it and many never do.
That’s why they don’t want us to shoot them.
It takes money out of the legal system !
They’ll all be out of work
