Numerous videos show capitol police officers holding doors open for protesters, waving them inside the capitol, escorting them around, etc. The blame shouldn’t land on those on the ground, because they found themselves in a losing battle and did their best (except Michael Byrd, he’s a cold-blooded murderer). You have to move up the chain to those who put them in that situation to lay the blame, up to the Capitol Police Chief, Sergeant at Arms, Nancy Pelosi, the DC Mayor, FBI DC Field Office Assistant Director, Agents and Analysts in Charge, and FBI leadership.
Whatever happened, happened. All the focus is on punishing the protesters and now Trump, while ignoring how and why there were systemic failures that allowed it to happened, and how to prevent it from happening again.
