Well, we can't blame the former TSA Administrator for this years round of tests and have yet had a naming contest for Pekoske.
Seems TSA is doing somewhat better than the 95% failure rate of the last testing that made it to the pubic but how hard is it to improve on a 95% failure rate?
I think this passage from the link in OP's post is interesting:
The congressman also noted that Viper teams, specially trained Homeland Security teams that use canines to secure transportation facilities, are being cut from 31 to eight.
Wasn't expanding the use of pooches suppose to be how to speed up TSA checkpoints?
2001 to 2017 and it seems that TSA is still flailing away at doing things that minimum pay contractors were doing adequately and for way less than
$8,000,000,000.00 taxpayer dollars each year.
