The door was his last defense against what? An unarmed woman walking down the hall? Possible vandalism?
An unarmed woman?
Did you see all her buddy thugs?
You don’t know that she was unarmed. She may have very well been carrying a knife. I don’t know that either.
Her buddies may have been armed as well.
There are several possibilies but, she and her buddies had no business breaking into the capital, fighting with the police and making their way down to the floor, where several Senators and Congress people were.
Hmmmm...
Let’s try this:
If she were no danger, as you insinuate, then by your reason should the police have invited her in, shook her hand, bade her to take a seat and offered her a refreshment?
What if they didn’t have her favorite beverage and she lost her mind?
Then what?
