You should be the defense attorney for all of the lawsuits that are coming to MGM and Mandalay Bay.  I read your excuses as lots of arm waving that the victim's attorney will cut through with ease on their way to a large settlement.  Every death will likely result in high 7 or 8 figure settlement, every injury will be at least 6 figures.  But that "do not disturb" sign defense might work.  You never know.
