We should close the Washington Monument entirely. Let it stand, empty and inaccessible, as a monument to our fears...

Some call terrorism an "existential threat" against our nation. It's not. Even the events of 9/11, as horrific as they were, didn't make an existential dent in our nation. Automobile-related fatalities -- at 42,000 per year, more deaths each month, on average, than 9/11 -- aren't, either. It's our reaction to terrorism that threatens our nation, not terrorism itself. The empty monument would symbolize the empty rhetoric of those leaders who preach fear and then use that fear for their own political ends...

The empty monument would symbolize our war on the unexpected, -- our overreaction to anything different or unusual -- our harassment of photographers, and our probing of airline passengers. It would symbolize our "show me your papers" society, rife with ID checks and security cameras. As long as we're willing to sacrifice essential liberties for a little temporary safety, we should keep the Washington Monument empty.

Terrorism isn't a crime against people or property. It's a crime against our minds, using the death of innocents and destruction of property to make us fearful. Terrorists use the media to magnify their actions and further spread fear. And when we react out of fear, when we change our policy to make our country less open, the terrorists succeed -- even if their attacks fail. But when we refuse to be terrorized, when we're indomitable in the face of terror, the terrorists fail -- even if their attacks succeed.

We can reopen the monument when every foiled or failed terrorist plot causes us to praise our security, instead of redoubling it. When the occasional terrorist attack succeeds, as it inevitably will, we accept it, as we accept the murder rate and automobile-related death rate; and redouble our efforts to remain a free and open society.

Every society accepts some risks as part of its overall social contract. People die when they drive cars, they die when they drink, they die from crime, they die when planes go down, they die on bikes. The only way to eliminate the risks would be to eliminate the activities -- no driving, no drinking, no weapons of any kind, no planes or bikes. While risk/reward tradeoffs vary between, say, Sweden and China, no nation accepts the total social controls that would be necessary to eliminate risk altogether.

Yet when it comes to dealing with terrorism, politicians know that they will not be judged on the basis of an "acceptable level of risk." They know that they can't even use that term when discussing the issue. ("Senator Flaccid thinks it's 'acceptable' for terrorists to blow up planes. On Election Day, show him that politicians who give in to terror are 'unacceptable' to us.") And they know for certain that if -- when -- a plane blows up with Americans aboard, then cable news, their political opponents, Congressional investigators, and everyone else will hunt down any person who ever said that any security measure should be relaxed.

This is the political tragedy of "security theater."

 

Last spring, a group of scientists at the University of California at San Francisco (UCSF) including John Sedat Ph.D., David Agard Ph.D., Robert Stroud, Ph.D. and Marc Shuman, M.D. sent a letter of concern to the TSA regarding the implementation of their 'Advanced Imaging Technology', or body scanners as a routine method of security screening in US airports. Of specific concern is the scanner that uses X-ray back-scattering. In the letter they raise some interesting points, which I've quoted below:

• "Our overriding concern is the extent to which the safety of this scanning device has been adequately demonstrated. This can only be determined by a meeting of an impartial panel of experts that would include medical physicists and radiation biologists at which all of the available relevant data is reviewed."
• "The X-ray dose from these devices has often been compared in the media to the cosmic ray exposure inherent to airplane travel or that of a chest X-ray. However, this comparison is very misleading: both the air travel cosmic ray exposure and chest X-rays have much higher X-ray energies and the health consequences are appropriately understood in terms of the whole body volume dose. In contrast, these new airport scanners are largely depositing their energy into the skin and immediately adjacent tissue, and since this is such a small fraction of body weight/vol, possibly by one to two orders of magnitude, the real dose to the skin is now high."
• "In addition, it appears that real independent safety data do not exist."
• "There is good reason to believe that these scanners will increase the risk of cancer to children and other vulnerable populations. We are unanimous in believing that the potential health consequences need to be rigorously studied before these scanners are adopted."
  

Pity poor Leif Ericsson. The Viking explorer may well have been the first European to reach the Americas, but it is a certain Genoan sailor who gets all the glory. Thanks to evidence that has until now consisted only of bare archeological remains and a bunch of Icelandic legends, Ericsson has long been treated as a footnote in American history: no holiday, no state capitals named after him, no little ditty to remind you of the date of his voyage. But a group of Icelandic and Spanish scientists studying one mysterious genetic sequence - and one woman who's been dead 1,000 years - may soon change that
