Those shirts are pretty cool. I think they'd be cooler if the text *only* showed up on the scanner. HOWEVER, I don't think the fourth amendment applies here. They're not grabbing you out of public and searching you. They're saying, "IF you want to get on this plane, we're going to search you." No different than a private business having the right to refuse service to anyone for any reason. IMHO. The thing that pisses me off about airport security is that the only Quiznos around here is in the Columbus airport, and you can't get to it without a plane ticket. FML.
