Misguided prosecutorial discression leads to new Fast and Furious

Fox News:

In a case that is prompting comparisons to the botched Operation Fast and Furious, police believe explosives found at a murder scene in Mexico may have come from an American bomb-maker whom the U.S. attorney in Arizona refused to prosecute.

According to an internal U.S. Department of Justice memo, a "Kingery grenade" was among the 10 explosives found at the scene of a shootout between police and drug cartels in Guadalajara on Oct. 10 in which three officers were killed.

The "Kingery grenade" refers to those manufactured by Jean Baptiste Kingery, a California resident who made grenades in Mexico from parts sourced in the U.S. He also converted AK-47s from semi- to fully-automatic weapons.

ATF agents arrested Kingery in 2010, but the assistant U.S. attorney in Arizona at the time, Emory Hurley, referred to the grenades as harmless toys and told the ATF the case "lacked jury appeal," according to the ATF supervisor in charge, Pete Forcelli. Forcelli had handled the case until the U.S. attorney declined to prosecute.

I think the only way to fix these problem is with an election where a Democrat does not win.  They just don't care when these things occur.  If they did they would not have gone to bat for the administration on Fast and Furious.
