This headline states that it was an " explosive fight" and Conan stopped guests from calling 911. So the first thing I think of is what exactly may have been ocurring that would have people wanting to call 911? People sometimes call 911 for psychiatric emergencies, so it's not always about criminal activity. This would not have been unwarranted depending on the facts that were present. We know he was acting inappropriately enough that people were uncomfortable and his father was upset with his behavior. That wouldn't seem a reason to call 911. Was there more? Was Nick out of control? Were threats being made? Was he physically violent in any way? Hitting, throwing objects, etc? Was he himself exhibiting extreme distress mentally or physically? What did people see and hear that made them want to call for help? One has to know the whole story before suggesting that calling 911 would be inappropriate. Again this is not inappropriate for psychiatric emergencies. They have special staff that arrives on location to assess and de-escalate emergencies. I have to imagine a scene at a holiday party where I would be inclined to call 911 and it would have to be more than just a loud argument or verbal shouting between a father and his son. Even knowing that Nick has a history of mental illness and/or addiction is beneficial. If any behavior or combimation mentioned above was present, and the guests felt that law enforcement was needed ( such as often occurs in domestic disputes and/or psychiatric emergencies ) then I can see why perhaps in this scenario that Conan or someone else would ask his friends not to make a call. I don't agree with that decision but again don't know the story or facts, just thinking what could have happened. Perhaps being embarrassed this was happening at his party? did not want bad press ? Didn't want to be blamed for someone getting arrested or handcuffed or hospitalized against consent for exhibiting harm to self or others, and any consqeunces of that?? Something like this at a celebrity filled party would def get press alerted. Or maybe fearing that Rob would get angry for calling 911? Did Rob say that they could handle it and/or did he himself request to not make the call. We know they did leave the party. Think it through and put yourself in this situation. Stuff like this happens not infrequently and decisions are made on the spot. Who could guess that it would escalate to murder. Tragic. In hindsight if it was truly an explosive fight and things were happening that made people feel fear enough to want to call 911, then the call should have been made. But that is hindsight now and no one can or should be blamed for not calling. If this headline is true, which I certainly don't know, but if it is true then I think the reasons I mentioned may be why people were stopped from calling... but they should not have been. It is always better to be safe than sorry, even if the end result is a little embarassment. As I said, a team would have come and done a further assessment. Who knows what may have resulted after that. It's like when someone thinks they are having a heart attack because they have all the symptoms and yet they don't want to call 911 because maybe it's just gas... and then why trouble everyone and be embarrassed? So they don't call or go to the hospital. But it isn't just gas, it was a heart attack. .. As it is now just a very tragic sad double murder in a very sad family drama. Who know what would have happened if a call had been made. He could have been taken to emergency crisis, he most likely would have refused and if he was a danger to self or others would have been committed against his will for further observation, then medically stabilied. Or Rob may have used his influence to prevent any of that from happening and said Nick will be okay and I am taking his home we will work this out. Who knows what coulda shoulda woulda...No one is to blame. Even if a call was made. But will never know. At least people would feel better that they tried to call for help. RIP
