How Pedro Pascal's Smarmy ATF Agent on SVU Got Taken Down By Benson and Stabler

A clean-shaven Pascal played U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Agent Greer (whose first name was never revealed).

Greer was a younger agent and a recent transfer to the New York office, having previously served in Laredo, Texas during an agency scandal. 

That scandal involved an undercover operation called "Short Fuse," in which agents gave guns to Mexican arms smugglers, hoping to track the movement of the guns to various drug cartels. 

Instead, a U.S. Border Patrol agent was shot and killed with one of the weapons, causing a scandal that unraveled the operation and some agents' careers.

Greer had been using Eddie Skinner, a career criminal, as a confidential informant inside a cigarette smuggling ring in New York. Skinner, meanwhile, had become the lead suspect in the murder of Annette Fox, a rape victim in a case that the SVU had investigated. The trial of her rapist, celebrity hairdresser Luke Ronson, was scheduled to begin the week after her murder.

After Benson and Stabler arrested Skinner for the murder, he called Greer to get out of prison and Greer obliged. The squad and the ATF agreed to send Stabler in with Skinner for a bust, but Greer jumped the gun on the raid, allowing Skinner to run off.

Greer gave chase, and Skinner grabbed a crowbar and hit the agent in the head before escaping.

He was shot and killed while in the custody of the NYPD.

Following the botched ATF raid, Stabler and Benson picked up Skinner, who cut two deals to reduce the severity of the murder charge. He first flipped on Ronson, claiming the rapist had described the crime to him in great detail before paying him to harass Fox to keep her from testifying.

Skinner then flipped on the person who had given him the gun he used to kill Fox. He explained that Greer had given him the gun after he had became an informant, despite his criminal history.

It turned out that Greer had acquired the gun amid the "Short Fuse" scandal, filed off the serial number, brought it to New York City, and provided it to Skinner. He was arrested for his role in the case and put in a holding cell at the SVU with Ronson and Skinner.

While the three men were awaiting transfer to Central Booking, Fox's teenage daughter Jenna came to the squad room to see the men charged in her mother's rape and murder. She then opened fire in the squad room, killing Greer, Ronson, a nun who was a witness in the murder case, and another police officer. She also injured Skinner — who survived at least briefly — and another police officer before Stabler shot her as she attempted to shoot Skinner again.
