A former hit man turns tour guide:
Mr Cullotta became an FBI informant in the 1980s, served time in prison, and said he had since struggled to figure out how to make a legal living.Back when things were probably actually more legit than they are now...
"It is a challenge to do things on the legal side," Mr Cullotta told The Daily Beast.
"Sometimes the legal isn't so legal, you know what I'm trying to say?
"There's graft in anything you do, even on the legal side. It's difficult to be legit, and I am legit. But I'm always having to fight the system for some reason. It seems like nobody wants me to be legit."
Mr Cullotta had the idea of leading a bus tour, and the 75-year-old obtained permission from the Las Vegas authorities to take visitors around scenes of murders and casino scams.
