I take your point about taxation in general, nacthebel, but let's not take this into OMNI/PR territory. Like many in TS/S-land I don't believe it's a proper for a gov't agency to stratify air travelers into haves and have nots through pay to play schemes. Because ultimately these p2p schemes create perverse incentives for gov't agencies to keep upgrading schemes regardless of effectiveness while facilitating an environment of fear and mistrust among travelers. Screen for IEDs and weapons and let us all be on our merry way without added fuss.
