Good, because behavioral profiling -- done properly -- works much more effectively at catching bad guys than do random screening and confiscating shampoo bottles.

Bad, because it won't be done properly. This stuff does work if the agents/officers have proper training and a fair amount of field experience applying it, but TSA supplies neither training nor experience. The contracts to administer the actual end-point security at airports are jobbed out on the traditional government system of nepotism, connectedness and bargain-basement low bidders.
