JC cops were brave and effective enough to put down the violent terrorist attempt to kill as many Jews as possible in 2019 with minimal loss of life, and they don't routinely murder or assault innocent JC citizens.

They're better than average.

Low bar? Sure. I wish every police department checked the boxes of "protect the citizenry from a mass murder attack" and "don't actually mass murder the citizenry yourself," but the question was about the average, not the ideal.
