You think you're so clever whipping out your iPhone to film police when they're giving someone an ill-judged whipping.
Well, the police can fight back, you know -- technologically speaking.
Officers in Laurel, Md., have decided that the way to prove that they are fine, upstanding policemen -- and sections of the populace are not -- is to get into wearable tech.
It's not quite Google Glass, and they won't look quite.
However, attaching a little video camera to their shades or, say, their hats will apparently avoid doubt.
As Laurel Police Chief Richard McLaughlin told CBS Baltimore: "It's kind of easy to have a he-said-she-said scenario, but when it's on video, you can't argue the facts."
Perhaps he's never heard the term "lawyer" before. Perhaps he's never watched a slick-haired smoothie persuade a jury that black is white and gray is merely dirty.
There's a certain joy, though, to expect from technology that is more mobile than a dash cam.
There's a certain expectation that these cameras will produce new angles on old facts.
On the other hand, this new police-infused version of Google Street View will surely throw up images of ordinary law-abiding citizens in the throes of intimate or even embarrassing private activity.
What if those images leak online?
Conversely, what if an officer forgets that he's off-duty and leaves the camera rolling? What delights might we expect from the shades-cams then?
