I'm curious what the proper TSA response should have been considering I have now seen the same people first bashing the TSA folks for being heavy handed and second bashing the TSA for publishing the video (which to my untrained eye appears to be the raw footage) which shows Emmerson's actions were contradictory to her story.

The TSA, IMHO, did not start this "pissing match" but since they had relatively easy access to the video chose to pretty much put an end to it.

How (in explicit details for my simple mind) should the TSA have handled this situation? The validity of the liquid ban is not in question here because most of us already find that absurd. But given the liquid ban fact what should the TSA have done differently?
