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.
