I think you should partner with scanner-protesters worldwide... create airport flash mobs with all protesters wearing your T-shirt synchro-singing "Lay Your Hands On Me" (Peter Gabriel's, not Bon Jovi's... although Thompson Twins had an applicable version too).
Land of The Free? and this design can coexist quite nicely I think... they tackle the issue from completely different but equally effective angles. Land of the Free? is largely sociopolitical in its content, employing the iconic power of the most well known symbol of freedom the US has to make a broad political point. Airport T Shirt takes the vantage point of the personal experience, the nitty gritty of the reality by satirising the experience, but also pointedly disagreeing with the lengths to which privacy is being invaded. I love both. I bought Land of The Free?... and I want a copy of this one too because they're both brilliant pieces of agitprop design. So yes Threadless. print this one.
