1) they opened the doors...after multiple other officers had been mob beaten with weapons and overrun in other areas of the capitol and it was clear they needed to fall back to protect themselves and those working inside the capitol since attempting to keep the mob out had been shown to get cops beaten down.
This doesn't alleviate anyone coming in the capitol of posing a threat because now the doors are open.
2) You're flat out wrong on the warning LOL. Big whiff on this one dummy.
"Baranyi was seen next to her in videos and photos of the incident. He gave an interview with a news reporter after the killing, showing the reporter the blood on his hands.
"[W]e had stormed into the chambers inside and there was a young lady who rushed through the windows," Baranyi told a reporter cited by the FBI affidavit. "A number of police and Secret Service were saying get down, get out of the way. She didn't heed the call and as we kind of raced up to try to grab people and pull them back, they shot her in the neck, and she fell back on me."
Also, who gives a fuck if the cop was in plain clothes. Doesn't matter when a member of violent mob breaks through a barrier to advance on cops and politicians using it for their safety. "but but but...he was in a blazer" is only an argument some one who is getting flailing would make.
3). "Waaaaaahhhhh George Floyd"???? This is just some odd emotional outburst. You should close sherdog and go outside and take some deep breaths because you're kind of spazzing out pretty hard here.
