This guy's trying to give Joe Arpio a run for his money as the biggest wingnut sheriff in Arizona. It seems he's gone from fearmongering over refugee children crossing the border to warning hikers to be ready to take the law into their own hands if they're out hiking this Memorial Day weekend: Arizona Sheriff Paul Babeu is advising citizens thinking of going hiking in Pinal County to "be armed, and do not be a victim" of drug cartel hitmen. According to the sheriff's office, Mexican cartels are sending assassins, or "sicarios," across the border to kill rival-cartel "rip crews" who ambush their drug runners and make off with money and supply. The office said there have been multiple gun battles in areas south of the county between cartel assassins.
