the problem with the argument that these checkpoints violate your rights and are impeding upon your freedoms, you would have to assume that you are truly free in the first place. never in the history of this nation, or any other for that matter, have the people been truly free. no matter what you do, you will always have to operate within the parameters of laws that someone else has made for you to follow, and the only way to change that is through "that which we can not talk about here". even then we would likely elect/appoint someone else to make new rules for us again.
A less invasive, militant, security obsessed, nannyish government could easily provide laws that embrace freedom and the rule of law. You don't get that when government tries to legislate things based on statistics, and sends its agents to confront people based on what they might do in the future.
that being said, some of you need to step away from the keyboard and go outside. I promise there is no boogeyman waiting outside your door to stomp your brains out.
The same cannot be said at a checkpoint.
73% of Americans support their use. The SCOTUS says they are legal. So it boils down that we don't like them and there isn't a damned thing we can do about it.
The fact that the zombie-ish public supports it as well as the tyrants in power, does not say much. Wrong is wrong.
That's where peaceful civil disobedience becomes necessary.
