Yes, the feel-good fiasco continues. If it's cool and you have a suitable jacket with lots of pockets, use it in place of a bag. Cargo shorts are good for smuggling all manner of contraband. You'll trot right through.
Epcot stinks because the bag check is right in front of the turnstiles. All the other locations the bag check has moved far in front of the turnstiles. You can get your stuff back together before digging out your park passes.
If you put your stuff up on the table with the zipper open they look, some more thorough than others. If you act inconvenienced and 'forget' about your waist pack they will look through every zipper. The stuff crammed in the bottom of the stroller - pull it out, too.
We've been five times since 9/11. At first they couldn't touch your stuff, litterally, they'd used sticks or flashlights to move stuff around while looking. This last trip they handled the bags a lot more. Don't know what the change was.
I think the security checks are either a liability limiter or a soothing balm. They are not enhancing security IMO.
