He's investigating the president's birth certificate, which is dumb for a whole host of reasons, the chief one being that the state which issued it has vouched for its authenticity.
This part is awesome though:
Arpaio has said he took deliberate steps to avoid the appearance that his investigation is politically motivated. Instead of using taxpayer money, the sheriff farmed it out to lawyers and retired police officers who are volunteers in a posse that examines cold cases. Other posses assist deputies in duties that include providing free police protection at malls during the holiday season or transporting people to jail.He's using volunteer posses instead of state resources and he thinks that will avoid the appearance of a political motive? Bullshit. If this was a valid issue, why not use state resources?
Oh yeah, because that would be a misuse of state resources.
Maricopa County is going to have a big job cleaning up the Sheriff's office when Arpaio is gone. Good luck with that, idiots.
