I once applied for a TSA job. The application process was over a year long.
"TSA is useless."
Yeah... about that...
"TSA officers caught 6,301 firearms at checkpoints this year as of Friday, such as in carry-on bags. About 88% of the firearms were loaded, the administration said."

@deadweirdo Agreed. But, imagine the "deterrence factor" wasn't there, either... Guns are actually easy to spot on the scanner (part of the testing in the application process is a simulation of using the scanner).
Hand searching each carry-on would be labor intensive... But, scanning and hand searching really should be the way it's done.
