You have to have reasonable cause to stop or detain an American. Stopping everyone is the exact opposite of that.
BTW- I got some time to debate it if you want to start another thread. I am passionate about it.
So I assume you oppose randomly stopping truckers to check whether they are in compliance with weight and vehicle maintenance regulations. Since there are usually no outward signs of non-compliance (probable cause), and since non-compliance poses a great risk to other drivers, should we just take our chances on the highway and hope that the 18 wheeler bearing down on us has good brakes?
