I posted this before but I'm not sure if anyone read it. A lot of news rooms have access to the emergency services radio. All newspapers have a section for police news. That is crime, accidents, suicides and the like. Everytime someone makes a call to 911, the newsroom knows about it through the radio. I don't think they hear the actual call but the call the operator makes to the police, the ambulance and the firemen about whatever is going on. I worked at a small spanish language newspaper in NYC and they had that radio so imagine the bigger ones like the Daily News, the New York Times. TMZ definitely has that radio.
Most celebrities know about it. I have been told that everyone works closely for any celebrity has to sing a confidentiality contract that means not just not talking about their private lives to the press but also that they are required to follow some silly protocol or procedure in order to ensure privacy. That includes not calling 911 right away. I think that's why the masseuse called Mary Kate Olsen and she sent her private security people to assist Heath instead of calling 911.
The masseuse called 911 shortly before 3.30 pm. By 4.30 pm there was already a mob outside Heath's building probably because the press found out about it through the radio. They know where celebrities live. Maybe they didn't know at first it was Heath but they knew it was someone important. That's precisely what the masseuse and Mary Kate Olsen were trying to avoid. I agree that she should've called 911 right away but we don't know the constraints the masseuse was in when she found Heath passed out, so lets cut her some slack. I think it was a damned if you do, damned if you don't situation. Granted she might have saved Heath life but also would've risked losing her job. The problem here is the system. I think the police should not grant the press so much access to information, and ban the use of such radios in the newsrooms.
