There are certainly educational benefits to filming ERs and frequently crews would not be able to get permission from patients prior to filming. So personally, I see no problem with the filming. But, before any viewings or editing of the recording, permission should be gained from the patient or –if the patient did not survive– the patient's family. In the United States, something like what happened to the Chanko family should absolutely be prohibited by HIPAA and the hospital should be severely fined!
