If you haven't done so yet, go and vote. You still have three and a half hours left ;-)
Quick, someone send this to George W. Bush (and a bunch of similarly reality-challenged politicians around the world). Not that I think it would help any...
There's quite a bunch of interesting comments in Bruce Schneier's blog. Basically, everyone seems to think that such measures are just plain stupid. I tend to agree.
I notice more and more misdirected efforts to "secure" our world. I'll tell you a secret: terrorists most probably won't publicly photograph any targets, they'll do it covertly, using cell phone cameras or very small miniature cameras, or whatever. Measures such as forbidding photography of public buildings simply annoy tourists, artists, or random people who like photography.
What's next? Forbid email, because terrorists could use it to communicate? Forbid planes, because terrorists could use them to destroy buildings? Forbid snail mail, because terrorists could send letter bombs? Forbid cars, because terrorists could crash them into shopping malls?
Can you spot a pattern here? You can't just forbid perfectly sound and non-malicious activities or technologies to "battle terrorism" — that's just plain stupid. You will piss off a lot of people. And it won't help anything to stop terrorists.
Update: Waaaaah! Now they try to abolish broadband Internet on planes (or at least they want to spy on you) — after all, terrorists could trigger bombs using the Internet. Yeah... I can't believe how fucking stupid some people can be.
