Oh, great, now they're adding two more 'layers'.

Let me count the layers:
-secure flight
-entry to checkpoint (am I attempting to enter the right line?)
-TDC - blacklight, squiggles, say my name
-second BP/ID check (only at some airports currently)
-BDO conversation
-'extra screening as needed'
- 'line director' - WTMD or NoS
- goods on belt, NoS scan
- grope because NoS scan operator is incompetent or asleep
- bag check
- BDO conversation starting at food court, continuing into bathroom stalls
- gate ID and bag check
