Why didn’t they shoot?

Since the January 6^th insurrection, and let’s make no mistake it was an insurrection. I’ve been asking the question, “why didn’t they shoot?”, they in question is the Capitol Police. Only one shot was fired from an officer standing at the door of the Senate floor. One versus the sixteen into the body of Laquan McDonald, one versus the six into the body of Michael Brown, one versus the ninety shots fired and sixty go into the body of Jayland Walker.
