This time the system worked. They kept the fight outside the U.S. Capitol. I have heard the same mantra from former House and Senate sergeants-at-arms and U.S. Capitol Police chiefs for decades now. "Keep the fight outside," they’d say. One former USCP chief always insisted to me the Capitol was secure. Until it wasn’t on Jan. 6. There was tragedy at the Capitol again on April 2. Police say 25-year-old Noah Green rammed a blue Nissan Altima into USCP Officers Billy Evans and Kenny Shaver. Green then plowed the car into a reinforced steel barricade blocking his route to the Capitol, jumped out and wielded a machete. Officers shot and killed Green.
