Note: This story has been updated with new information from Las Vegas Sheriff Joe Lombardo, who disputes MGM’s claim that police responded to the 32nd floor immediately.

At least two Las Vegas police officers and two armed private security officers were on the 32nd floor of the Mandalay Bay hotel during the time that Stephen Paddock was firing down into a concert crowd, killing 58 and wounding hundreds, according to a statement from the hotel’s owners, MGM Resorts International. Should those officers have tried to stop the massacre, knowing at least one person was firing a high-powered rifle and they probably had only semiautomatic pistols?

And did they notify anyone of the location of the shooting? Las Vegas Sheriff Joe Lombardo has repeatedly said police didn’t know that a security guard had been shot until four more officers climbed the stairs to the 32nd floor at 10:17 p.m., 12 minutes after the shooting started and two minutes after it ended. The shooting was a month ago today.

The conclusion that the four officers were nearby during the massacre is inescapable from the statement issued by MGM Resorts. It was first sent on Oct. 12 to clarify the timeline of events which involved the shooting of security officer Jesus Campos near the outset of Paddock’s onslaught, and whether Mandalay Bay alerted police to the Campos shooting. MGM said, and Lombardo agreed the next day, that Campos was shot at about 10:05 p.m., and reported the shooting within 40 seconds of Paddock beginning to fire out of his suite at the end of one 32nd floor hallway.
