This is how the truth gets made
Now that the bogus story about photographers needing permits has (although inadvertantly) hit the mainstream in a "serious" publication, you can almost see the process working itself out.
Some people will think that it's a good idea. Others will think it was already illegal - either for anti-terrorist reasons or misplaced "think of the children" notions. The politicians will sit on the fence - and when there's no public outcry, will realise that here's a liberty no-one cares about - or will miss. They'll be able to score a minor and temporary "tough on crime(?)" victory with little or no criticism.
Meanwhile anyone with a camera will become a pariah. Photography will become something that can only be practiced discretely, then with explicit permission, then in the privacy of your own home, then not at all. In the meantime, the do-gooders and politicans all pat themselves on the back for making us all a little safer.
Much more of this safety, and no-one will be allowed to do anything.
