It is dangerous to quote the United States Constitution in America
Here's a cool idea: Write the Fourth Amendment on your chest in a marker, and then refuse electronic scanning at an airport, henceforth removing your shirt and thus displaying the Fourth Amendment. Actually, it's not a cool idea, Aaron Tobey used this technique of self-expression, and here's what the TSA did, as described at Lowering the Bar:
they cuffed him, interrogated him, had the airport police charge him with "disorderly conduct" (favorite of official thugs everywhere), and then contacted the cops at his university and suggested that they report Tobey to the Dean of Students.Here's a copy of Tobey's lawsuit. A link provided in this same article suggests that the body scanners used at many airports might be emitting ten times as much radiation as previously claimed.
