Demi Moore's recent health emergency has prompted a Los Angeles official to challenge laws that allow media outlets to broadcast 911 calls.

The redacted phone chat between one of Moore's friends and an operator detailing the actress's possible drug use and condition was released by police last month and has been played on TV and radio shows as well as over the internet.

Los Angeles politician Norma Torres was sickened by what she heard and is now spearheading a campaign that will better protect the privacy of celebrities who fall ill or suffer medical emergencies.

Torres states, "Everyone has the right to privacy. The unauthorised release of medical records is already illegal, medical emergency calls should also be protected."

Torres is a former 911 operator, according to the Los Angeles Times.

Paramedics were called to Moore's Hollywood home on 23 January after the friend called emergency services to report the actress was convulsing and semi-conscious.
