U.S. Attorney Richard Donoghue himself urged a jury Monday to convict a man accused of shooting an on-duty FBI agent in the back.

“If I were to walk up behind Mr. Navarro right now and shoot him in the back, you’d think ‘he just tried to kill that guy,'” Donoghue said of his startled-looking co-counsel, assistant US attorney Francisco Navarro, during closing arguments in the trial of Ronell Watson. “And you’d be right.

“Mr. Watson intended to kill when he aimed that loaded firearm and at Agent Harper’s back and fired,” he stated.

FBI Special Agent Christopher Harper, who testified against Watson, sat in the front row of the gallery alongside his wife as prosecutors argued that the reputed Crips gang member was guilty of attempted murder of a federal officer, assault of a federal officer and possessing and discharging a firearm during a crime of violence for the broad daylight Dec. 8, 2018 shooting in Canarsie.

Harper testified he’d been on a surveillance assignment with a group of other agents, and was FaceTiming his wife when Watson approached his vehicle, acting “shady.”

Defense attorney Michelle Gelernt said Harper had been distracted Watson approached his car, and scared her client — who has compromised vision — when he gunned his engine and sped away.

“Ronell Watson was no assassin,” she said. “He’s just as afraid of agent Harper as agent Harper is of him.”

Gelernt said her client viewed “the occupant in that car as a danger or a threat,” after the home he shared with his mother, girlfriend, and daughter had been repeatedly robbed.

During the week-long trial, jurors were shown surveillance footage of the firefight, and were even escorted to another part of the courthouse so they could view the bullet-riddled vehicles themselves.

If convicted, Watson faces up to life behind bars.
