To describe the current behavior as "confiscating pocketknives" isn't even accurate - third party testing of how well the TSA actually detects and confiscates items like knives, guns, and (fake but real looking) explosive devices shows that they miss the vast, vast majority of items. Like more than 90% of them.

Nobody who wants to succeed would bother going through TSA.

'Known Crew Member' goes around TSA. Even TSA goes around TSA since they added the shiny metal badge on their shirts in 2008. Airport vendors bring in tons of product every day through side gates.

Strong flight doors which are locked and better procedures stop the hijackers.
