You went to Las Vegas with your friends, just taking a week to get away from it all. There were four of you sharing a hotel room.
Las Vegas has very carefully and intentionally developed a reputation throughout the country and even the world as a city where anything goes -- so much so that many visitors are surprised to find that they can get arrested for crimes here as in any other city.
For those in other parts of the country, Las Vegas may seem like a bubble of no-consequences good times nestled in the desert. While it is true that Sin City allows its patrons a good deal more freedom than other parts of the country or even the world, it is not a place without laws.
