I believe that non-citizens are attempting to hide by wearing TSA uniforms. Everybody wearing a TSA uniform should be stopped by ICE officers and, if they can't provide proof of their citizenship or legal status (i.e. a passport or green card, driver's license doesn't prove anything), they should be held until they can show such proof.
