This is my first time venturing into this forum (and it might be the last after what I have to say), but I feel very strongly about this topic and so I'm going to comment.
I have an alternative solution to the current backscatter technology: millimeter wave. It's less invasive (the image received is far less detailed, allowing agents to see if there's a threat without seeing the details of a passenger's naked body) and there is no threat from radiation. Passengers get to keep their modesty and airline workers can rest assured that they're not going to put their health at risk simply by going to work, and everyone's allegedly safer. So why not use millimeter wave instead? Seems like a no-brainer to me. Well, because Rapiscan, the backscatter people, lobbied Congress hard and heavy and bought their way in, that's why.
If you feel that this is just the way it has to be, who says it will stop here? We're in slippery slope territory now. In 2009, a man hid a bomb in a place where the sun doesn't shine in order to try to assassinate a Saudi prince. If something like that happens in our country, should we then offer ourselves up for full body cavity searches at the airport in the name of safety? Why not, if it keeps us safe, right?
And for those of you who say "if you don't like it, don't fly", I'm thinking the terrorists are saying that to themselves, too. We have two huge open borders to our country. They could drive themselves in and blow up who knows what and do a lot more damage than blowing up one aircraft. So why stop with scanners at airports? How about getting scanned every time you want to go to the mall, or to the grocery store, or to worship? After all, terrorists could be anywhere. We need to be safe!
I'm sure there will be many of you who will think I'm some overwrought hysteric, and that's your right. I'm secure in the fact that I'm not one of the sheeple who do anything they're told and never question *if* they should be doing it or not. Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety. Some old dude named Ben wrote that, but what the hell did he know, right?
