While nothing they do short of disbanding will make some people happy, TSA is making some sort of effort. I think in a few years the WTMD will be a thing of the past and the checkpoint experience will consist of some combination of Advanced Technology (AT) Xray machines, some type of body scanning machine and possibly these shoe scanning machines.
