To some criminal defense lawyers, the government’s pursuit of Miami lawyer Frank Quintero Jr. on money laundering charges is a prime example of the federal assault on lawyers who represent accused drug dealers.

On Tuesday, at the end of his second trial in five years, Quintero walked out of the Miami federal courthouse a free man after jurors acquitted him on six counts. Earlier, U.S. District Chief Judge Edward B. Davis had acquitted Quintero on two money laundering and laundering conspiracy counts.
