Yet somehow it will never occur to ANY Police Union to announce that they will proactively weed out bad officers to prevent them from throwing the entire country into a crisis.
It is not the job of any union to weed out bad employees, it is the unions job to represent all employees not just the good ones. This includes Teachers, Cops, Autoworkers and many more.
The only solution to remedy this is to abolish all unions, good luck with that.
