Nejame and Lester and O'Mara are all friends and as such I think Lester knew he could walk all over O'Mara without a peep from him. I think that O'Mara realized that he was the laughing stock around the courthouse, agreeing with everything Lester said and did, and leaving his client out there to hang.
He finally found his backbone, or perhaps he read the blogs and heard what everyone was saying about his incompetence, or perhaps the Zimmerman family told him to defend George or resign. Anyway he finally after three months did something that showed guts. Let's hope he follows through.
Remember that it was O'Mara who got Reckseidler to step aside, leaving George with one less disqualify the judge card. So this just might an effort in futility which has been MoM's MO all along. That's hardly a strategy.
Reckseidler was disqualified on (d)(2) basis, conflict of interest. There is an unlimited number of these available to both sides in the dispute. Zimmerman used two, sort of by accident, as the court's next pick was a judge who knows O'Mara socially (O'Mara is godfather to the judge's son).
The motion to disqualify Lester is on a (d)(1) basis, the judge is prejudiced, biased, whatever you want to call it. Each side gets one of these "for free," and after that, subsequent (d)(1) disqualifications happen only if the judge agrees he is biased.
