The TSA is an excellent example of a well intentioned, well-thought out government program that was fucked from the word go.

They pay decently, which means the guberment agency was completely iunudated with demands to hire not the best people for the job, but "equally"
Their training is at best, laughable, and there is a lot of truth to the statement they are given more training about how to work the system and keep thier jobs than how to properly perform thier jobs
The worst part is they know they are ineffectual, and thier job has no meaning beyond harrassment and that they are resented, so few if any give a rats ass about actually doing a good job.
