Ludicrous. Hospitals are where the sick and dying go for treatment. Police are there to Protect and Serve. Terrorists try to kill you. Why do the former do more damage than the latter?
I agree that the headline is sensationalist, but if you don't think we've got a real police problem, your head is in the sand. Fortunately, the solution isn't that difficult (body cams), and is essentially around the corner.
Personally, I think disarming the police would have a lot more effect than body cams.
Cops already function as defacto surveillance machines. The bodycam doesn't capture any more than the cop does with his/her own eyes and the cop has the authority to act based on that alone, the bodycam is at least an impartial representation of the cop's (or citizen's) allegations.
However, the problem with technology is the scale. You can't systematically collect everything a cop sees in a database; with a camera, you can.
