> So police should be exempted from mass surveillance ban ?!?

Whatever the solution ends up being, I want the police to be the same as everyone else with regard to that solution.

I don’t really get normal human psychology, so I don’t know if everybody or nobody should have facial recognition software in public places, but I do think it should be a choice of “everybody or nobody”.

Police is here to serve the public, so naturally public may want to impose rules on police which it doesn't want to impose on itself. It all depends on who wants what (and for what).
