This wasn't some officially sanctioned camera, there for the purpose of accountability. It was a personal camera a firefighter had placed on his helmet. My guess is, it was already in violation of department policy, and only tacitly allowed (every department I know of has a policy against using personal cameras on scenes). This is likely just a clarification that they will now be enforcing this policy.
I'm shocked this policy wasn't enforced sooner. The number of HIPAA violations that must have resulted from the use of these cameras must be staggering, and I'm surprised they haven't been sued yet.
We're not law enforcement officers. We're not there with a warrant, we're there to provide care and compassion. Shoving a camera in someone's face without their consent is neither good 'care', nor is it compassionate.
