Some valid points have been posted here, either way, regarding the bag checks. If they're really using them to stop food & drinks - that's great....seems wasteful, but whatever.
I don't really buy the fact that the rent-a-cops checking bags are highly trained experts in profiling and spying....they just look like jolly old men to me. Now, there may indeed be plain-clothed security profiling at the gates, and I'm all for that. They don't hold up the process and they don't cause a distraction, scene or sense of worry to "grandmas" who have become agoraphobics since 911.
I often wear a very compact belt pack for my digital camera - and about half the time, the guy standing in the NO BAGS line tells me he has to check my camera pouch. What?!?! I guess he's looking for the extra bullet in the battery pouch that I might use in the .38 I have strapped to my thigh.....
If I were a bag checker, I would indeed participate in profiling - whether it's PC or not, it happens....and I'm sure after 911 we ALL have caught ourselves doing it at least once. If I'm checking bags and I see mom and dad and bobby and susie with mickey ears on - yeah, I'm just gonna give their bag a quick scan for beer or the forbidden outside food. However, if I see a Muslim-looking gentleman, perhaps with a turban and/or Muslim garb on...and he's alone or with another male of similar appearance, I'm probably going to disect their bag - I'll admit it. Call me racist, call me cautious, call me whatever you want.....and I'm not alone. If the checks are indeed necessary, then I hope (and presume that) they are profiling in some way - even if they're just looking for some roudy teens or suspicious loners.
As perviously stated on the X-Ray system....it won't slow down the process like at other parks, or airports, because it won't be that system. They will be better concealed and won't have alarms that the public would hear or see. They will simply display almost a true-life video of each person walking through the X-Ray field - allowing the plain-clothed security to identify suspicious objects and their location on someone's body - then they can, very casually, pull that person aside upon entering, and give them an opportunity to present that object, or be subjected to a quick pat down. This would all be done in a room adjacent to the entrance, and all the other guests would see is someone that appears to be a Manager or other street-clothed CM speaking with a guest in a pleasant manner - giving no sense of alarm.
