I suspect the same holds true in ABQ. The TSA here are amongst the worst in the country for standing around and being clueless*. The swabbing looks like make work or a side act to the theater. This is especially true since they have 3-6 people standing around watching the process. They often have ABQ P.D. or CBP folks watching as well. It's amazing how disgusting it can be.

* - As other have mentioned, the cues for the scanner become horribly long. It's outrageous to see a dozen clerks standing around chatting on the other side. They can't even pretend to do a gate check well, rarely doing anything. In one case, a crew of three didn't do anything or speak to a single passenger. The more senior person on the crew hid in a corner and played with his smart phone (before he found a seat for some much needed rest). The other two were hanging out chatting with him, occasionally looking at his phone and laughing. I'll guess YouTube.
