When the Mob Museum downtown opens later this year the Tropicana will have already beaten Oscar Goodman to the Punch. The Las Vegas Mob Experience opened on Christmas day. It is an interactive museum with more than 1,000 artifacts from reputed mobsters with ties in Las Vegas. One of those mobsters is the man who built the Flamingo in the 1940s, Benjamin "Bugsy" Siegel. We talk with Siegel's daughter Millicent and a historian from the museum about the attraction and Las Vegas's history with the mob.
