It wasn't stopped because some goofball cult member broke through a police barricade intent on harming lawmakers, then ate a bullet. It was stopped when Trump - knowing he was responsible - broadcast a video calling off his rabid dogs and told them to go home.
No, the Steele Dossier predates the attack on the Capital by unhinged Trump supporters. The statistics on police injuries due to MAGA violence is:
• 140 police officers were injured or assaulted during the attack: roughly 80 U.S. Capitol Police and 60 Metropolitan Police Department officers.
• Officer Brian Sicknick died the following day after responding to the attack. The medical examiner ruled his death was from natural causes (two strokes); Capitol Police regards it as a line-of-duty death.
• Four additional officers who responded to January 6 later died by suicide.
