"How did a stun gun find it's way into a passenger's seat back pocket?", is the $64,000 question. The stun gun disguised as a cell phone was found by the cleaning crew after the plane arrived in New Jersey from Boston. Nobody knows how it got there.
Given the lack of security on planes and on the tarmac, I'm surprised strange incidents like this don't happen more often. There's a huge gapping loop hole in security at airports and I'm not speaking about the ineffectiveness of the TSA.
True facts: there are no background security checks on employees working as cleaners, rampers, mechanics, caterers and probably other airport workers I haven't even thought of. AND, these workers DO NOT, I repeat, DO NOT go through TSA security checks before they report to work on the tarmac or aboard a plane.
The million dollar question is "why?". Especially when the traveling public is treated like criminals by a handful of power mongering TSA employees who should be fired on the spot for there insensitive, rude, offensive, abhorrent behavior.
Update: Reuters reported four hours ago that two more stun guns were found in a passengers luggage in New York.
