Many problems with this...

• Highly questionable value given (a) effective lack of terrorists, (b) the other "layers" of TSA security, (c) the numerous loopholes that allow people to bypass the NOSs anyway, and (d) the millions of sheep who don't care about privacy and Constitutional rights
• Doesn't address SDOO through alternative gate selection
• Not a priority (e.g., not as important as scanning airport employees and vendors and not as important as scanning cargo)
• Potential to add yet more delay and confusion at checkpoints
• Excessive expenditure of public funds (for equipment procurement, additional staff, training, maintenance, etc.)
• Confirms that the current TSA process is flawed (which we already knew but TSA apparently just figured out, despite years of NOS infestation in our airports)
• Ignores relevant public comments on NOS (e.g., designed to support NOSs when most of the comments clearly indicate NOSs are offensive)

Where is the cost-benefit analysis? Which vendor is this lined up for? And has TSA already decided that it will ignore the public comments on the NOS NPRM?

EDIT: Will this randomizer split up families? And how will the TSA ensure that I go to the designated lane? Will the document checker keep an eye on me? Will the randomizer keep a record of what lane I was assigned to so as to prove that I did not go to the designated lane?
