The VIPR is a cousin/off shoot of the TSA, as piglipstick describes:
Thanks to TSA Chief John Pistole’s determination to “take the TSA to the next level,” there will soon be no place safe from the TSA’s groping searches. Only this time, the “ritualized humiliation” is being meted out by the Visible Intermodal Prevention and Response (VIPR) task forces, comprised of federal air marshals, surface transportation security inspectors, transportation security officers, behavior detection officers and explosive detection canine teams.
These teams will be (and are already are, in some places, but get ready for soon they'll be everywhere) in malls, schools, stadiums, arenas, train and bus stations... they don't need your permission to search.
This isn't about our safety or protection from terrorism (the latter of which, we cannot be "protected from" since it's terrorism. Think about that very harsh and chilling fact) but it is everything to do with control. As piglipstick ends his post with, this is the TSA motto posted at the TSA office in New York:
“Dominate. Intimidate. Control.”
