It's a frightening situation to be in: You're in a casino, and the lights go out. It could be an entirely innocent situation. But what is the first thing you should assume?
In the outage at Paris Las Vegas, a construction crew accidentally cut the main power line and the backup. So, in this case, it wasn't anything sinister. But in general, Lt. Randy Sutton says the hotel-casinos on the Strip go to extremes to keep the lights on.
"If the electricity goes off and it stays off, that's an indication that there's a problem, and you need to figure out a way to get out of the hotel," said Sutton.
Until you know otherwise, you might want to assume the worst, such as a terror attack or a well-planned robbery, and be aware that someone may use the outage as a crime of opportunity.
Lt. Sutton says that in a situation similar to the one at Paris Las Vegas, you have to take responsibility for your own safety. He also thinks hotel security and law enforcement might look at their response to see if they can learn anything in case it happens again.
