Shift in White Collar Probe Tactics a Mark of Breuer’s Tenure

Lanny Breuer, the U.S. Justice Department’s outgoing criminal division chief, said prosecutors have a new paradigm for corporate crime investigations, with wiretaps and insider witnesses becoming core components in the search for fraud convictions.

Breuer, often criticized for his division’s inability to bring criminal cases against Wall Street executives in the wake of the 2008 financial crisis, said he will leave his position March 1 after helping to implement tactics “that simply haven’t been used before.”
