If you visited D.C. in the days before COVID and January 6 madness, and wandered around (or got permission to go into) the Capitol, you saw Capitol Police officers on duty. They were doing pretty much what all police officers do, which is to stand guard at vulnerable spots, making sure no one did anything naughty (e.g., graffiti) or downright dangerous (e.g., gun or knife attacks). However, beginning with January 6, 2021, it became apparent that Nancy Pelosi's Capitol Police officers have a different mandate: defend the Democrat party hold on power.
On January 6, the Capitol Police failed to protect the Capitol. We know this because Capitol Police chief Steven Sund, after being fired on January 7, 2021, explained that he had requested backup from the National Guard, which never arrived, and that his people just weren't ready. Trump stated that he had requested that 10,000 National Guard troops be deployed to the Capitol before January 6 to provide protection for his rally. According to him, congressional leaders said no. What really happened remains a mystery despite the "investigation" by the January 6 Committee. You'd think they would have figured that one out.
Also bizarrely, on January 6, someone (the Capitol Police?) opened from the inside the Capitol's 20,000-pound doors, which are secured by powerful magnetic locks. We then saw footage of the same Capitol Police graciously welcoming people inside, which led many innocents to believe they had the perfect right to be inside the People's House.
For those of us (like me), who think January 6 was an entrapment scheme, it would appear that the Capitol Police were part of the plan.
And if you're inclined to distrust the Capitol Police, you're not going to like hearing what happened last November to Congressman Troy Nehls, a Republican from Texas who has locked horns with Nancy Pelosi. According to him, the Capitol police entered his office illegally and took pictures of confidential information on his desk:
