The cops can only ignore what the taxpayers (who insisted in the stupid laws to begin with) will let them ignore.
I don't think the taxpayers insisted on "stupid laws" like seat belt requirements or yearly car registrations/car tag requirements and fees. Those are just a couple of examples where 'discretion' should seemingly be used more often by the officer.
They insist on them being enforced. I've heard people complain about a lack of enforcement on all those things. I ignore them anyway, but people still complain about me ignoring them.
