US Law enforcement does what it's told (more or less) and acts on the orders of the various governmental entities, from the Federal level on down to the tiniest incorporated entity with it's own budget and cop. Some politician or bureaucrat decided how to do this, not a cop.

Do you really still think that the US government pays attention to any of the constitutional stuff?

I wish with my whole heart that they did. All that civics crap from the schoolbooks is little more than propaganda. It's been roundly ignored since way before I was born.

Too many lawyers, too many overlapping laws created simply to make a politician seem busy for his sheep before for election time, too many politician's bought and sold.
