The first paragraph of this LA Times piece says a mouth full.
Police have dramatically changed their account of how the Las Vegas massacrebegan on Oct. 1, revealing Monday that the gunman shot a hotel security guard six minutes before opening fire on a country-music concert — raising new questions about why police weren’t able to pinpoint the gunman’s location sooner.
It reminds me of when I was distributing Waco: The Rules of Engagement. I would loop it constantly at gun shows and Preparedness Expos all over the country. People would watch a few minutes and see how the FBI was lying about their actions and say, "Well, now THAT doesn't make any sense. Why'd they do that...?" They would quizzically ask the question two or three times before it would dawn on them that asking the question gave them the answer. They were being lied to. They would either leave with a look of horror on their faces or buy a copy of the video.
Again, from the LA Times piece:
But Clark County Sheriff Joe Lombardo said Monday that Paddock shot Campos before his mass shooting — at 9:59 p.m. — and they now don’t know why Paddock stopped his attack on the crowd.
Because he was dead, thats why. He was shot dead by his handlers, probably before the mass murder began.
