I didn't agree with check points 30+ years ago, and I don't agree with them now. I would vote, but I would have to check off all the above, and there isn't a slot for that. While I am pro law and order, and I don't agree with most here on their opinion of ALL police, check points are just basically everything listed, and more.
I have worked them on man hunts, and it was a scary proposition stopping everything that came thru, but at the time there was an immediate need to do so. Check points for the sake of checking everyday traffic, in my opinion is unlawfully detaining citizens going about their everyday activity.
On the other hand, should research of a given area show high activity of for instance illegal aliens driving unregistered, and uninsured vehicles I would say that such an activity, would benefit the legal residents of that area. Especially if their the ones getting run into by uninsured motorists.
There are many deal killers to paint this with such a broad brush, but generally I have stated my opinion.
