I searched for a thread and didn't see any mention of it.
I'm currently in CLT and on the landside away from the counters they have a table set up and 3 TSA screeners randomly asking people if they can check your ID and contents of your bag. I was asked and basically ignored them and walked away - I figured you have no authority till I go through the checkpoint. Yesterday in LIT I noticed a couple of them at the gate I was at and during the boarding process randomly asking passengers to see their BP and ID's.
I take it these are new "enhancements" to the security mission?
