Homeland Security, and its subsidiary organization the TSA, are able to function only because the US is currently under an extended State of Emergency. Protections against illegal search and seizure are suspended in specific situations. If you live within 100 miles of the border, if you are travelling on public transportation, or if you are suspected of terrorist ties, these protections do not apply. Suspicion is the only requirement, and just-cause need not be present.

TSA searches are now gutting the few remaining Fourth Amendment protections against search and seizure. Essentially, our government, supported by the courts, has defined a "Constitution-Free Zone" incorporating all airports and the area of the United States within one hundred miles of a border or the coast (termed the "functional equivalent of the
border, or extended border"), in which constitutional protections under the Fourth Amendment are deemed not applicable, and are routinely flouted by the Department of Homeland Security.
