If the North Hollywood Shootout is to the up-arming/up-arming/up-militarizing our police force, then I guarantee you that THIS incident will cause just about every public servant to think about either investing in their own GoPro camera (or equivalent body cam) on their own dime, or city/county/state attorney's will demand that their LEOs wear them.
My opininion? I want all cops to be issued a firearm, a radio, a dashcam with microphone, and a body cam.
Cameras are getting smaller and cheaper. I say the more LEOs wear them, the better. Just make sure that no one can muck with them after an incident.
Absolutely. With sensible compression, full-HD 24/7/365 video can fit on a 1TB drive for $50. Cell-phone style cameras are tiny. I’m surprised nobody is making a minuscule clip-on one that you just have to insert a small battery and 64GB MicroSD card in, letting you record continuously for a month and costing $1/day to run.
