The FBI agents were serving arrest and search warrants on him when they opened fire.

According to the complaint, Robertson had posted to social media on Monday, “I HEAR BIDEN IS COMING TO UTAH.”
“DIGGING OUT MY OLD GHILLE SUIT AND CLEANING THE DUST OFF THE M24 SNIPER RIFLE,” the post continued. “WELCOM, BUFFOON-IN-CHIEF! (sic)”
Robertson had been on agents’ radar since at least March 19, when the agency’s National Threat Operations Center received a tip from an unnamed social media company that a person with the username “@winston4eagles” had posted a threat to kill New York County District Attorney Alvin Bragg.
“I’ll be waiting in the courthouse parking garage with my suppressed Smith & Wesson M&P 9mm to smoke a radical fool prosecutor that should never have been elected,” the post read in part, according to the complaint.
As agents continued to investigate Robertson, they found more social media posts that appeared to indicate Robertson owned numerous firearms, including a sniper rifle, as well as a ghillie suit, and had made “violent threats to murder public officials.”
One such post, which appears to have been made to Facebook in 2022, according to the complaint, read, “THE TIME IS RIGHT FOR A PRESIDENTIAL ASSASSINATION. FIRST JOE THEN KAMALA!!!”
The posts also indicate that Robertson intended to impede, intimidate and retaliate against the FBI, the complaint states. One such post read, “HEY FBI, YOU STILL MONITORING MY SOCIAL MEDIA?”
“CHECKING SO I CAN BE SURE TO HAVE A LOADED GUN HANDY IN CASE YOU DROP BY AGAIN,” the post continued.
