I am not familiar with Mr. Bunin, but those folks that I've heard from who do know him are giving very glowing reports about him as a defense attorney and administrator.
He's got a big task ahead of him. The PD's office is going to have to find a place to house itself, and then find the staffing necessary to manage the caseload it is tasked with. It will be interesting to see where Mr. Bunin will recruit those new Assistant Public Defenders from. As an anonymous, large, Irish defense attorney friend of mine suggested, perhaps the pool will come from departing Assistant District Attorneys, but I kind of doubt it. Most prosecutors that leave the D.A.'s Office generally leave for the freedom of being their own bosses and the opportunity to make more money. A transfer over to another government entity would seem to negate those goals.
Either way, the months and years ahead are going to be interesting for Mr. Bunin and the Public Defenders Office. I wish him the best of luck.
