""We didn't know anything was going to happen, and I wasn't at the office yet, but my coworkers and my dad were here," Lund told the Washington Examiner."
"So were the EPA agents, who cornered his father. The elder Mr. Lund calmly got out of his car to be patted down by an armed EPA agent wearing soft armor."
"“It was 12 armed federal agents, and they had little EPA badges on and everything. I come in about 10 minutes later, and there was one agent out there,” Lund said. “He walked me in, and they had a search warrant for conspiracy to sell defeat devices. They basically went around the building, and they did forensics — physical forensics, digital forensics on the laptops, and we were compliant.”"
"Following the EPA’s December National Compliance Initiative, which focuses on manufacture, sale, and installation of emissions “defeat devices,” the agency targeted the high-performance auto industry, sometimes deploying armed agents to slap heavy fines on violators."

"“I think it’s insane that over 40 executive branch agencies have police forces. The EPA shouldn’t be able to raid anything or anybody,” Rep. Thomas Massie, a Kentucky Republican, and co-sponsor of the RPM Act, told the Washington Examiner."
