Several hundred US agents raided Oklahoma and New Mexico stables this week and arrested seven members of Mexico’s Zetas cartel for laundering drug money through the horse tracks. A total of 14 defendants were charged with conspiracy to use horse racing and breeding to launder more than 20 MUSD of the cartel’s drug money.

 

In the 1940’s Las Vegas and the Mafia were synonymous. It seems like money from the mafia still have an impact.
