As an example, cops show up on most EMS calls around here. I must admit, I find it a bit disquieting when a cop wearing a camera walks in while I'm providing care... Especially since HIPAA does not cover cops, so there is no legal protection for the information that ends up on the camera, only department policy. I would feel much better if I at least knew it was going to be automatically redacted, with the original video only available under a subpoena.
