Five lives were lost on 1/6. There could easily have been thousands of lives lost on 1/6 - we got very lucky, it wouldn't have taken much for it to have gone to a very bad place.
Three rioters died from medical emergencies, one was shot by police, and the Capitol Police officer's death was never conclusively linked to the events of the riot.
What's your idea of the sequence of events where a crowd of unarmed people in the Capitol "easily" would have led to thousands of lives being lost?
