ABC 33/40 - Birmingham News, Weather, SportsMob museum newest attraction in Vegas

Las Vegas earned the nickname "Sin City" for several reasons. A new museum in the city honors one of them. The museum is devoted to mobsters.

It's the second mob-themed attraction to open in the city within a year. The first one did not do well and has already shut down. The city says this new attraction will do much better because it is more authentic. 

The museum is housed in a former federal courthouse where a U.S. Senate hearing on organized crime was held in the early 1950s.

Las Vegas thought it would be fitting to open the museum on this day. Eighty-three years ago, the St. Valentine's Day massacre took place in a Chicago garage.

Seven rivals of mobster Al Capone's gang were gunned down.

It is the most notorious gangster killing of the prohibition era.
