Someone Mailed Explosives to Sheriff Joe Arpaio

An explosive-filled package addressed to Sheriff Joe Arpaio in his Phoenix headquarters had only made it to Flagstaff when authorities found it. They confirmed explosive material had been discovered after the package was flagged as suspicious, and they "contained the material with no injuries," according to AZCentral. But beyond that, police aren't making many details public about the incident. Death threats against the high-profile, rabidly anti-immigrant birther Arpaio are relatively common. But based on the initial report, this looks like a step up from a threat to an actual attempt.
