Correct. They're also rapidly rehired in neighboring jurisdictions. Public sector unions aggressively protect officers ability to migrate to new jurisdictions despite being fired for cause. Typically they end up working at less prestigious operations, and the chronically-fired ones bounce around until they're in the sticks, working as a deputy in a small county.
All of these officers will have new jobs lined up by the end of the week.
You think unions shouldn't be looking out for their members?
It's not on the unions, it's on the people who hired the officers.
