Oh, right

I've frequently observed non-uniformed but airline ID carrying people breeze through security with no liquid limitations enforced. Not enough for a charade bypass huh?
Take a deep breath, think it through.
Fact: Explosives exist in many physical forms. Banning liquids completely does not effectively exclude explosives. Explove exclusion should be your agency's goal. And the cunning terrorists have recently, as many on here predicted, switched to powder in their choice of explosives.
Fact: Allowing liquids past checkpoint charlie as long as they're in portions < 100ml doesn't limit how much liquid can be accumulated in the "sterile" area.
Fact: The dozens of exceptions, including the flight crew exception, to the <100ml limit furthers the ease with which mass quantities of liquids can be accumulated in the "sterile" area
I call charade. It would seem the reason your agency instituted a >100ml liquids ban is because liquids readily show up on the X-Ray, so readily that even the dullest X-ray operator can recognize and confiscate them. The occasional airline traveller may actually walk away impressed that the ever vigilant TSA is so good, they can intercept potentially dangerous liquids in a travellers carry-on without so much as a hand search.

The fact that there are so many exceptions to the liquid rules, and that all these dangerous liquids accumulate in open containers, right there at checkpoint charlie, fray the edges of your circus tent. TSA's actions, in total, prove to critical thinkers that this is all a witless theater, which can only impress some of the infrequent flyers passing through the TSA's 3-ring act.
