LAS VEGAS (AP) - Stadiums, corporate buildings and other facilities that draw crowds have strengthened their security since 9/11 and earned U.S. protections if their efforts fail to prevent a terrorist attack and they are sued.
But hotels, including Las Vegas' world-famous casino-resorts, have not received the same safeguards. A publicly available database of all federally approved technologies does not list hospitality companies.
An expert says the constant flow of people may pose a challenge.
Four of the largest casino operators in Las Vegas would not tell The Associated Press whether they have sought them.
The law is now at the center of a legal battle after MGM Resorts International invoked it to sue hundreds of victims of the deadliest shooting in modern U.S. history to avoid paying out for lawsuits.
