About That Casino Safety? Maybe It's Overated

From The Las Vegas Sun: Terrell met four people selling merchandise — CDs or bottled water or T-shirts — on the Strip on July 6 or 7. The five helped each other, then decided to party that night. Someone got a room at New York-New York, where the five hung out.
The next morning, while the other four were asleep, Terrell took their wallets and made for the door. One man, described as very large, awoke and chased Terrell to the elevator. There, Sisolak was told, the man hit Terrell, who fell and was knocked unconscious. Thinking Terrell was still alive, the assailant retrieved the wallets, returned to the room and fell asleep. That was about 5:40 a.m.
For six hours, Terrell lay on the hallway floor near the elevator as hotel customers stepped around his body entering and exiting the elevator, according to what Sisolak said he was told by Metro.
Finally about 11 a.m., resort security got involved. Terrell was still unconscious but alive, Sisolak said he was told.
Terrell was taken to a hospital, then taken to a different hospital. He died July 9 at Valley Hospital.

A guy lays in the hall for 6 hours and security doesn't find him? It's bad enough people are walking around him and not reporting it, but there had to have been an employee such as someone in housekeeping or someone else who saw him down.
This time, it was a two bit thug who got what was coming to him but what if it was a tourist who was having a heart attack or stroke? Or an innocent bystander who was robbed and mugged?
I guess, in Oceans 11 where Tess says there are camera's everywhere in a casino, well maybe not, or at least not at the New York New York. Why would anyone want to stay there after this?
