In theory, this could be a nice way to screen people... if you were smart enough to perform anomaly detection, and then investigate further based on that.
However, some min wage TSA employee digging through my personal information doesn't make me happy at all. All I see happening from this is a series of false positives and violations of privacy. Because its security theater in the hands of some sickening bureaucracy whose first goal and only goal is to grow like a cancer and protect its own institution.
Why we would expect more from a government that treats its own people as the enemy, by spying on everyone, by incarcerating more people per capita than anyone, who sells laws and regulations to the highest bidder, and whose elected representatives only job is to get reelected by garnering as many bribes as possible in the form of campaign financing, and live by a different set of rules?
Seriously. Why expect anything more? They aren't good people. They aren't honest people. They don't give a fuck about you. Your outrage is pointless. You are free until they decide you aren't... then they can just hold you in prison like Kevin Mitnick without even charging you with a crime, or bust you for a crime you didn't commit, or one of they many crimes you probably commit on a regular basis, and don't even realize it because there are so many laws. Including secret laws you don't get to know, and copyrighted laws you aren't authorized to read.
