Airport security

Hey guys,
This is my first post and I hope it wont seem gloom and doom that my first post is on airplane security but I want this blog to be news oriented and today I have been watching coverage on why the Christmas plane explosion got as far as it did. I have personal experience of getting through liquids, that I didn't realize were in my purse, and friends getting tweezers and other banned objects past security. I think that tweezers and my perfume bottle are reasons to worried- but those are things we ARE looking for and they are not being caught. So it doesn't surprise me that things we haven't thought of, exploding man-diapers, are not being detected. I am really confused how after such horrible attacks like 9/11 and constant terrorist attacks around the world that there are scanners that could catch these very type of things but because of bureaucracy and privacy concerns they are not largely implemented. I dont understand how someone can really complain that the strangers can see their underwear over being blown -up. If people really feel this strongly because of religious or other concerns, then railways still run. Drive or take a train. Airplanes are not a right, they are a business and they deserve to set their own standard for the safety of their vessels and customers.
I talked to a friend of mine who is a naval officer and works with CIA and he said that airplane safety is rushed because of the strict takeoff times and that the future of air safety is tentative take off and arrival times. You would board your plane when everyone has been checked and run through databases. There would be an arrival cutoff and then everyone would get checked. Once that was done then the plane takes off. It would be hard with connecting flights but I think that people need to realize connivence is not to be sacrificed with safety and we arent living in the same world as we were 20 years ago. We watched the countries be plagued with terrorist attacks and thought that we could never be there. Now we know we can be there, and we need to pull out every measure to prevent any attacks.
I also watched the press conference with President Obama where he said that he was done with finger pointing and the buck stops with him. This sounds horrible to me. I want whoever is in change of connecting databases that would have send him or whoever didn't flag the fathers call about his son going rogue to Yemen with an extremist group to be fired. Finger pointing is useless but pointing out where things weren't wrong and fixing them by hiring someone who would do it better is not. This is not bureaucracy, this is how any high-level company would operate. At any news agency or large corporation there was a melt down of this capacity, there would be people who were fired. This also doesn't send a good message to terrorists abroad, they will know the same people that let this happen will still be in place the next time they try to attack us. They are learning from their failure as much as we are and now they know they wont have to worry about change of command and a change in mind-set. We still are only preparing for past attacks and not looking to the future, which wont be explosive underwear.
