The checking was a visual check. I was driving so I thot it odd they look in backseat for my seatbelt. It was a shakedown, pure and simple for whatever they might turn up, the "law" for my security mind you, gave them the pretext to stop me. I suspicion that had I had something of interest in the backseat, they would have "asked" permission to search.
They cannot even do a visual check to the back seat without cause by law unless you give permission. Like I said if people do not put the police on notice at check points then they will take a mile. Now if your hiding something well then your playing with fire. They can slow you down and obsereve if your wearing a seat belt and or if your vehicle registration is valid, if they are then they have to let you pass. If their not, then they can stop you.
In many States the cops stand near a traffic light to do this. You have to stop and they can observe. But search? No way. Like I said, these check point are getting out of control.
