You can't call it "baseless" (or even a witch hunt) merely because you weren't informed of the base for the search. You don't know. Therefore you cannot assume. You just assume they were there to randomly harass people, but you don't know that for a fact. It might not have been random at all, they may have been checking very specific vehicles that fit very specific descriptions. A truck driver gets woken up and sees them checking a few vehicles, but not all vehicles, so he assumes it's random, but he doesn't know, either.
"But truckstops are supposed to be our safe haven!"
Says who? Truckers?
"When a PEACE OFFICER invades that sanctity and randomly interogates truckers, I don't see that as keeping the PEACE. Do you?"
Well, when you put it that way, no, I don't. If they are indeed randomly and without any foundation or direction whatsoever interrogating truckers, then not only is that not keeping the peace, it's highly illegal, even under the broadest, most liberal interpretation of the Patriot Act. And if that was, in fact, what happened, I find it hard to believe that a number of lawsuits haven't already been filed and we don't have the ACLU crawling all over Effingham, not to mention that anything that merely hints of litigation is an OOIDA wet dream (and even they failed to pursue it beyond a couple of phone calls).
Oh, and don't kid yourself, a truck stop is not a sanctuary, not a sacred place that can afford immunity from much of anything, and as such, cannot have its sanctity invaded. There is nothing illegal about knocking on the door of a parked vehicle, even a truck, in a truck stop. I've had van drivers, truck drivers, and the police knock on my doors at all hours of the day and night. The ones that I were the least outraged with were the police.
There's also nothing illegal about asking if a dog can search your cab and sleeper. You can let 'em, or not, up to you. You know when you're driving down the road and you pass by a 4 wheeler where a cop is searching the vehicle and all the stuff if laying on the side of the road? That driver gave the wrong answer.
