Disney is the one place I feel I can let my guard down, a little. I've watched the security people and they have gotten very thorough in their bag checks. I've seen people try to go through the bagless line, but they were stopped. I also noticed, on my last trip in March, a young man who was bagless, but his cargo shorts were full of 'stuff'...the pants were actually drooping!!! He was made to go through the 'xray' scanner, after emptying every pocket...man, he was peeved!!
Once inside the parks, there are cameras everywhere, watching and yes, probably 'profiling' people. There are plain clothes security people...I always wonder if it's the tubby guy in the sandals with black socks and the white belt on his madras shorts!!
I suppose that if someone really wanted to get in, with some kind of chemical agent, it might be possible. But, there's only so much I can worry about. I try to be aware of my surroundings. And I always know how I'm going to get out of a place in the event of an emergency!!! Yes, I am that worrier mom!!!
