Then the taxpayers should probably object to how the police behave. I mean WTF is the damned perpetrator supposedly costing the taxpayers here? Why in the world even offer an argument like this?

When you object to being punched in the face, the problem is the punching in the face not the objection! If the bystanders don't like the fallout, "accept your punching more quietly and without spilling my drink" is not among the valid responses.
