It would make more sense to have a licensing body or multiple that are all connected, use the same processes and can strip a license.
Doctors, nurses, lawyers, teachers all over the US already have licensing requirements, ongoing training requirements etc.
Edit to add: I live in Minnesota and Philando Castile was shot and killed by a Saint Anthony police officer in Falcon Heights. Falcon Heights used neighboring Saint Anthony’s department for their city as well. Outsourcing to another agency/department doesn’t address root cause of policing issues.
I think part of the problem here is the news media and how the stories are framed.
The headline should be that obstinate companies refuse to share the profits and meet reasonable union demands, which will cost them millions.
