IF it were voluntary and IF it were free of charge (ala INSPASS), I would welcome a TTP (Trusted Traveler Program). I would happily supply my Passport number, residency info and proof of my extensive travel for the past five years. Being as though I've already been fingerprinted, even if that were asked for I still wouldn't mind.
But that's just me!
I'm sick of the unwarranted hassle as much as anyone. It's just that it's not going away anytime soon and I'm unwilling to continue to put up with this screening BS if the folks who granted power to the TSA to touch my breasts lest I be denied travel say I can sidestep it. Period.
