It appears the 4th amendment certainly still applies in the 100 mile zone, and if it did not that would be insane. According to that page, 2/3 of the population lives inside the 100 mile zone.
The CBP officers do apparently have more leeway as far as detaining a person roadside (see 'reasonable suspicion'), or boarding a bus/ train and the like, but probable cause is still required to search a vehicle, or arrest a suspect.
"An immigration officer also cannot search you or your belongings without either “probable cause” or your consent. If an agent asks you if they can search your belongings, you have the right to say no."
In the past, I have successfully denied an officers request to search my vehicle at a routine traffic stop. He backed off immediately. It is easier said than done, being stopped by law enforcement is always stressful. But simply saying in a polite manner, 'No, sir. I prefer you didn't search the vehicle', is one of our greatest tools the 4th amendments provides us.
Officers WILL ask and try to gain consent if at all possible. I suspect that most of the vehicles the other commenter saw being searched by the roaming patrol, either did not know they could say no, or did not have the nerve to say no in a tense stressful situation.
I know that's what the courts say, I just think it's insane and indefensible. And that erodes my trust in our judicial system and my respect for our institutions.
Or it would, if I had any left. If the law doesn't apply equally to everyone, it's not a legal system so much as a way to selectively keep people down.
