Thanks for the reply, AKK. I really don't have any credentials, to speak of publicly, so these are merely my thoughts and position based on observation. As mentioned, I'm not anti-TSA, per se, as I agree the mere presence of security tends to deter some nefarious activity by those seeking to do us harm. In fact, I enjoy the professionalism of all the TSA agents I've encountered, thus far. Even if I felt they were cranky or plain not nice, they were very professional in nature. They are paid low wage and assigned a high degree of responsibility, so I have no beef with the agents, themselves.
I guess the concern I have is in regards to the reason behind the policies and procedures, as well as the consistency of their application. Underlying is the concept that government is reactive in nature. They need to be in most cases, as to do otherwise would be an infringement on our freedoms.
To that end, many of the more "tiresome" requirements (3-1-1 bags, no shoes, super sensitive metal detection, full body scans, etc) are in direct response to terrorist activities occurring on aircraft over U.S. cities, which originated in other nations (the show bomber, for instance). They are not due to a lack of vigilance by our own security and law enforcement agencies, and I perceive the restrictions more as the mandates by politicians needed to
appear proactive instead of providing any real security. Of course, the line TSA agents and supervisors may question the zaniness of a mandate; while, they carry out their duties, professionally as always.
I think this Freeze Drill is a reaction to a couple incidents, where people have made it through security with unsearched bags or contraband (for instance a woman that made it past security with a gun:
http://travel.usatoday.com/flights/...-dfw-for-bringing-gun-onto-aa-flight/606403/1). It could be effective, and I could understand the need for agents to make everyone "freeze" in place (not move) during a real breach, but someone should announce it as a drill, and permit greater flexibility during such tests, so a boarding is not missed or a person wets themselves who "really needed to visit the facilities"

.
As for example as to why I personally have the opinion that the TSA is mainly a perceived security instead of an actual one:

Mom gets $3.99 refund on peanut butter (the point isn't the refund, rather that the agent didn't confiscate the jelly, too, which to me is more jell-like

(this one gets me a bit, since if he was a real terrorist, he could have easily chosen several paths to get through security with illicit material. This was just for the agents to CYA themselves. While AKK may not agree, since it is a blogger, it is a personal account of activity, and since the person isn't anti-TSA, it has a bit of credence.)
In the end, I agree that a perceived increase in security has a deterrent effect that is valuable, and TSA agents are very professional. I just wish we could stop some of the more inconvenient aspects that really were initiated as a reaction to activities outside of our nation's security bubble.
