Benji - they don't have to do another photo recce. They've already done many. If they're doing more, they're doing it clandestinely, not with tripods and view cameras. Or even with film SLRs. It'll be digital happy-snaps taken on the fly. This is not a good argument for abridging the 1st Amendment. As Benjamin Franklin so aptly put it (I'm paraphrasing here), "Anyone who would trade liberty for security deserves neither".
