Driving is a licensed privilege not a right.
That's because the government told you that, and you accept it.
He's right. It is a licensed privilege and government has a right to patrol the roads for public safety but where the violating of rights occurs is through illegal search.
Does anyone remember the news story a few years back about Louisiana State Troopers stopping out of state folks with nice cars and illegally confiscating cash and vehicles just because they wanted them? If the citizens knew the reputation of that force , video camera and a knowledge of their rights I imagine they would have been able to keep from having their rights trampled on. It's not a perfect system but it is designed to protect us from an over zealous government more so than to protect us from unsafe situations.
