Laws are threats made by the dominant socioeconomic-ethnic group in a given nation. It’s just the promise of violence that’s enacted and the police are basically an occupying army. You know what I mean?
They violate rights and create revenue. In that order. It's most important they get your ID even if you aren't suspected of of a crime. If you doubt me, try telling them no sometime.
Besides... Being fired? Just like almost any industry, they just go a town over and get a job doing the same thing elsewhere. Unfortunately nobody wants to pony up a national agency to track such stuff. The closest we get is background checks and references.
I would rather they hire pigs who do nothing then not hire people and still expect those to pay taxes to feed the war coffers...at least that money is going back into the stream
