Wow....just wow.....
Just to add to what Guy Incognito, and TurtleDude said...
First, There are always other ways to get to where you need to go. It might not be as fast, but those other ways will still get you there. Other modes of transportation within the US are: private plane, car, truck, pickup, bus, train, motorcycle, moped, bicycle, and the oldest mode of transportation known to man...your feet. And none of them has the security protocols that the airport has. (heck you can even stick out a thumb and get a ride with a stranger if you think that you absolutely need to)
Second anyone and everyone just "has" to get to where they want to go and thinks that should trump everyone elses problems. Hate to break it to you but that is wrong. John Doe's wants/"needs" are just as important as Jane Doe's wants/"needs". And saving even one life is far more important than your want or "need" to get onto a plane.
Edit Note: Oh and if you have to go overseas there are private airplanes which do not require you to go through the TSA's checkpoints and there are ships. So either way you're covered going to another country also. (and if a buisness has enough money to need an employee to go to another country then by god they have enough money to spring for a private plane.)
