Via Hit and Run, an overwhelming case for openness in counter-terrorism.
The bullet points: If law enforcement had kept fewer secrets from the public, the Sept. 11 attacks would not have happened. If they had kept more secrets, the attacks would have been more successful.
Our key advantage over the terrorists in our midst is that there are more of us than there are of them -- by a factor of tens of thousands. Secrecy is a necessity for them: it evens the odds by taking nearly all of us out of the fight. If they know our secrets, there's actually not enough of them to exploit it. If we know any of their secrets, then someone, somewhere, can use that to learn more or to act against the terrorists.
In Britain, the government believes there are people against whom no legal case can be made, but who pose a huge danger if released into society. Its solution is to put them under house arrest, without legal proceedings, and a law is now before parliament to permit this. My solution would be to publish their names, addresses and photographs in the Mail on Sunday, and suggest that people might want to keep an eye on them.
There is, of course, a danger that "mob rule" might get out of hand, but I trust the people more than I trust the government. Apart from anything else, private individuals are more accountable than officials, as they do not have the Official Secrets Act to protect them from the consequences of their actions.
