Watch the London community support officers (they're not real cops, but deputied volunteers who fancy themselves real ones) as they confront a videographer who has the temerity to take footage of a public street. It starts with a sudden gloved hand over the camera lens, then it's "give me a good reason why you're filming," then it's on to "papers please"; and when the guy behind the camera, sensibly enough, asks under which law he's not allowed to film there, the bully-boy hisses "shut up." Twice.
To be clear, there is no law against taking photos — or video — in a public space. Not in the U.K., anyway. Not in the U.S., either. Know your rights, and assert them. If you let them atrophy, then, like never-used muscles, they begin to disappear.
UPDATE, July 1: Reader Cath Unsworth catches an error:
I love this piece, so in the interest of accuracy, I wanted to let you know that you've muddled CSOs with Special Constables. CSOs aren't volunteers — they're not proper cops, but they are paid.
Hereby noted, and apologies for the mistake.
