Close the Washington Monument
Bruce Schneier has written an absolutely powerful essay in his blog, with the modest proposal that in response to the security worries at the Washington Monument, we should close it.
If you haven’t read it yet, run, don’t walk, to his blog and read it. Then if you live in the States, write to your congresscritters, and ask them to reinsert the backbone which they have placed in a blind trust when they got elected, and tell the TSA that they have a new mandate; to provide as much security as possible without compromising our freedom, privacy, and American Ideals.
