Don't worry - you can pay ~$100 to have the privilege of being "randomly" selected for "reduced" screening (ie, pre-9/11, with a metal detector).
Of course, this is certainly not random at all. I don't have a random sample, but based on what I can see, it's very unlikely that they actually select people randomly and fairly[0].
The existence of this program means that we're separating travelers into two groups - those who can afford the $100[1] to be exempt from these draconian checkpoints, and those who can't (or who can, but are still forced to go through them anyway).

[1] Not just the fee, but also the time (you have to go for an in-person "interview", which is really just so that they can fingerprint you... I don't remember them asking any real questions)
