It's fine and dandy that we can sit over here in LJ-land and whine about how people are stupid and terrorists are stupid and the TSA is stupid and expecting us to keep flying the friendly skies when they take away everything that keeps them 'friendly' rather than 'homicidal' is stupid, but let's be honest: it doesn't do anything. It legitimately changes nothing, because our voices, loud as they seem to us, are entirely unheard by the people who matter in this.
How do we get heard?
We make them hear us. TSA Contact Information.
Phone: 1-866-289-9673 -- this is a toll-free number
Physical address: TSA-1 Transportation Security Administration 601 South 12th Street Arlington, VA 22202-4220 Wait a week or so for things to calm down, and then, if they haven't realized that they're being idiots, start contacting people. Tell them 'this does not make us safe; this just creates a new arena for road rage to explore'. Tell them 'I would rather have my tax dollars spent in avenues which actually increase security, rather than creating the illusion of security'.
And don't stop there. Write to your Congresspeople. Write to the Department of Homeland Security. Spend a few dollars on stamps, and make them listen. All the whining in the world won't change things.
