It used to be ridiculous.
No newsflash -- it still is.
Last week, I observed a screener who'd zeroed-in on an antique money-clip, with a 'hidden' 1" nail file. BIG to-do. Pax was allowed to find outside safe haven for the clip, then treated to shoes-on SSSS on re-entry.
Same pax carries in his wallet, a 2" stick-pin -- apparently no threat, because it's attached to his LEO BADGE.
Makes ya wonder
