http://news.yahoo.com/s/nm/us_security_airline_scannersI've said it before and I'll say it again, Terrorism is nothing new and continuing to take away OUR privacy and freedom is exactly what terrorists want. The simple fact is you can't stop terrorism and I felt after 9-11 that what the US did with Airports was absolutely the wrong direction. These scanners in my opinion take what is already in place and makes it even worse. I haven't flown since getting out of the Army and I HATE TSA. They are Aholes and I've dealt with them on countless occasions; even threatened with being put in a room because I didn't want them to go through my PACKED army bag (those of you who are in know what it is like to pack them) and refused to open the lock. It took 20 some minutes of me standing their in full uniform talking to supervisor after supervisor. It wasn't until other people started yelling at the TSA that they stopped harassing me. I also dealt with them at our local airport while serving in the Air Guard. These things are not good. I really think that cameras, these devices and what we have to go through to pay out the Ass and now have our naked bodies on camera just to fly are just a beginning. Sad thing is, it's just not in the US... Anyone see the program on the History channel about security technologies know what and where this is all going.
