The result is you’ll have no public servants.
Police, EMS, fire… everyone goes out and does the job at the behest of, and with delegated authority from, the public. It is only proper that the public also defends and indemnifies those people.
There’s an argument to be made that deliberate malfeasance should not be covered. And in my department, it isn’t. But truth be told, most lawsuits against the police aren’t about that. They’re money grabs.
I see your point but when public servants fuck the pooch, why do, we have to foot the bill instead of the trash that did the dirt?
