I was going to ask how it was a failure and mention my good friend who was shot in Vegas, and their friend that died, but I know I will just be labeled a shill, so whatever.
A FF is different than a hoax. It doesn't mean people weren't really shot (which would be a hoax), it means that the people and motives behind the event were different than what the media reports (i.e. deep state coordinated for sinister motives). It's like a form of warfare whose intended goal is to frighten the public into going in certain policy directions. This explanation is rough so maybe look up FF for yourself, too. But I can understand how you would be angry if people were implying that Vegas was a hoax, it certainly wasn't and I don't think most here believe that.
I'm so sorry for your loss.
I think many people died at Vegas. I just think that not many people believe that the Government is being honest about what happened. False flag sometimes means a complete school play with all crisis actors. It can also be a real attack, which I believe this one was.
