Photo-terrorism?

"Since 9/11, there has been an increasing war on photography. Photographers have been harrassed, questioned, detained, arrested or worse, and declared to be unwelcome. We've been repeatedly told to watch out for photographers, especially suspicious ones. Clearly any terrorist is going to first photograph his target, so vigilance is required," writes Bruce Schneier, BT's chief security technology officer in this story in the Guardian newspaper.

"Except that it's nonsense. The 9/11 terrorists didn't photograph anything," he says. Schneier questions the growing concern: "Given that real terrorists, and even wannabe terrorists, don't seem to photograph anything, why is it such pervasive conventional wisdom that terrorists photograph their targets?"
