In the first public speaking appearance of his 60-plus-day tenure, San Francisco U.S. Attorney David Anderson sparred with leaders of the local defense bar Tuesday night over his plans to use tactics more traditionally associated with fighting organized crime in white-collar cases and his goals of upping the pace of criminal prosecutions in the Northern District of California.

In a panel discussion sponsored by the Association of Business Trial Lawyers, dubbed “White Collar Crime in a High Tech World,” Anderson got some pushback from criminal defense icon Cris Arguedas of Arguedas, Cassman, Headley & Goldman and Patrick Robbins of Shearman & Sterling about plans he’s outlined since appointing his new leadership team within the office last week.
