He was already acquitted (in 2017), and then briefly hired back to the department which reimbursed PTSD related medical expenses and allowed him to retire on medical grounds with a $2500/month pension.

I'm of a mind that police officers should have to carry malpractice insurance like doctors and other professions do, and repeated incidents would jack their rates up and if they're out of control would be priced out of the profession, instead of moving to the next town over and continue dumping the lawsuit costs on taxpayers. But in this case even that wouldn't have done anything. There are bigger training and accountability problems.
