Pinkerton, the security company 9News said it contracted with for the protest, did not immediately reply to questions from The Post sent Sunday morning.
While Pinkerton had an active license to employ security guards in Denver, officials have no record that Dolloff had the required city license to work as a private security guard, said Eric Escudero, spokesman for the Denver Department of Excise and Licenses.
“We do not currently have an active license and have never had an active license for anybody with that name,” he said. “If he was operating as a security guard, he was in violation of the law.”
