How a security breakdown enabled an angry mob to take over the US Capitol WLS Share: Share: CHICAGO (WLS) -- Former Capitol Police Chief Terry Gainer said his old department was out-manned and outmaneuvered by violent extremists who were riled up by President Trump himself. Gainer, who is also a former Chicago cop and Illinois State Police director, watched the U.S. Capitol fall Wednesday to violent extremists, vandals and looters, most who were not from D.C. "What was unprecedented was the President of the United States at the other end of Constitution incited those people and really lit the match," he said.
