BAG SEARCHES
The bag checks and the finger scanning slows down the crowds entering the parks.
There are many undercover security people watching us as we enter the parks. If you know where to look you would see all kinds of "hidden" security cameras.
I have seen more of those cameras in the parks then i anywhere I have vacation except maybe with the exception of Vegas.
Since 911 WDW is a no fly zone.
Disney has spent mega bucks on security since 9/11 and it would not surprise me at all if along with those Bioscans Disney has or will have in near future.security devices such as Bomb-sniffing technology (there are polymer devices already in use that can pick up on tiny trace amounts of explosive vapors from over 20 feet away).
Or the full body backscatter X-ray (which has already been tested at the Orlando airport).
Have fun at Disney!
