SEARCH FOR INNOCENCE AND GUILT
Smith, a Harvard Law School grad who is not registered with any political party, started as a prosecutor in 1994 at the Manhattan District Attorney's Office under Robert Morgenthau, who was best known for prosecuting mob bosses.
"There was just a real emphasis, from Morgenthau on down, on not just going after convictions," said Todd Harrison, an attorney at the firm McDermott Will & Emery who worked with Smith in Morgenthau's office and later as a federal prosecutor.
"We were praised if we investigated something and demonstrated that the target of the investigation was innocent," Harrison added.
In 1999, Smith started working at the U.S. Attorney's Office in Brooklyn.
Smith was involved in the prosecution of Charles Schwarz, one of several former New York City police officers who were implicated in a high-profile police brutality case involving Abner Louima, a jailed Black inmate who had been assaulted by police with a broomstick.
Smith also won a murder conviction against Ronell Wilson, a drug gang leader who murdered two undercover New York City police officers, though a federal appeals court vacated the death penalty verdict.
In 2008, Smith left to supervise war crime prosecutions at the International Criminal Court in The Hague. He returned to the Justice Department in 2010 to head its Public Integrity Section until 2015.
More recently, Smith returned to war crimes cases in The Hague, winning the conviction of
Salih Mustafa, a former Kosovo Liberation Army commander who ran a prison where torture took place during the 1998-99 independence conflict with Serbia.
