Folks, these guys are willing to try anything to harm commercial aviation. Not bringing shampoo to your meeting is NOT the end of the world. Getting your plane blown up by a carry on Molotov cocktail IS.
There's a myriad of other threats... SAMs, freight, incompetent screening, etc. Most posters here at TS/S are against 'security' charades meant to appease the general (nonflying) public, such as the shoe carnival. The DHS itself has posted a report that said shoe carnival does not scan for explosives! All we ask for here is a bit of sanity in this. We want well thought of security measures that have one aim in mind: sensible risk mitigation that balances convenience, cost, and risk.
