In a small courtroom on the fifth floor of the Hall of Justice, Jeff Rosen made the final arguments of his last trial as a hands-on prosecutor on Tuesday. With thin fingers, he karate-chopped the air like a symphony conductor cueing the string, brass and percussion sections, except the players here were three accused murderers. “The buyer, the middleman, the hit man,” he called them.

There were cheers and hugs in the District Attorney’s office on the Friday that Jeff Rosen’s victory over Dolores Carr was announced.

Rosen spent Monday and Tuesday walking from desk to desk shaking hands with everyone in the office, and leaving handwritten notes for those who were out. Since he’d been on leave for the campaign, Rosen wasn’t carrying his entry badge, so the DA-elect had to go to the office’s information desk and be issued a visitor’s badge.

When he returned on Tuesday, he didn’t have a county-issued parking spot, so he went in to get a placard and returned to a ticket on the dash. Rosen says he wants to talk to the officer who issued the ticket, not to ask for a break but because the timekeeper wasted no time in writing the summons.
