Correctly initiating an investigation of the judge? Ha! IF an investigation of the judge had been warranted, Arpaio should have demanded an independent investigation, not just hired a private investigator to investigate the judge. You want to talk about a conflict of interest? There it is.
Take off your blinders - Arpaio screwed this one up, bad. Heck, his own lawyer resigned saying that he could no longer ethically represent him - any lawyer knows that that is a HUGE red flag.
I think Arpaio was trying make a preliminary investigation to see if there was even enough of a case there to pass off to an independent investigator and there wasn’t one!
People’s spouses say a lot of stupid things, especially when they are drunk!
In this case, the Judge elicited comments from a witness in open court after the fact involving his own wife! Now the judge is responsible for what HE does about his own appearance of conflict of interest.
Arpaio was already in the clear having acted properly prior to this trail as far as I am concerned, but IANAL.
