Good cops, and there are many, would be horrified by his behavior.
Sadly, with the police I know, I haven't found this to be the case. Policing is funded via extorted funds and the "service" is provided without consent of the customer. This renders the job itself illegitimate. I do have great respect for those that speak out against abuses such as these, but the ones that speak out have almost always already quit the "force" after their moral compass returned.
I agree police are funded with extorted funds, but that applies to a good deal of public services. Firemen, paramedics, schools to be sure. But also to the same extent road workers who are paid with public funds, hospitals and doctors who are reimbursed with public funds, certainly all of the military and coast guard, etc etc....
We can't equate being reimbursed with public funds with being morally compromised. The vast majority of individuals involved in the occupations I listed are good people trying to do a good job. And they are horrified when people step beyond the bounds of reason and abuse their power.
Doesn't change the fact that society would be better off if we limited the amount of occupations funded with extorted funds -- we are in agreement there.
