“The last thing that I want to do is say, ‘this could never happen again’ and have it sound like a challenge to those people,” said Capitol Police Chief Thomas Manger, who took over the department in August after his predecessor’s ouster following the siege. “I’m not trying to be overconfident. We are much better prepared.”

The story of that preparation is only partially written, though. Capitol Police officers remain overtaxed and exhausted, logging crushing amounts of overtime as they grapple with a depleted force. Threats against members of Congress are still spiking. A Sept. 18 rally to support certain insurrectionists drew an overwhelming police presence that dwarfed the smattering of demonstrators, raising questions about an overcorrection and quality of intelligence.

And with the atmosphere under the dome as personally corrosive as ever, it’s tough to say the Capitol has moved forward from Jan. 6. Many of those who fled from or responded to the violence are indelibly scarred.

“My concern about the Capitol Police is that we’re making them work too hard and too long,” Missouri Sen. Roy Blunt, the top Republican on the Senate committee that oversees Capitol security, told reporters recently. “And we need to figure out a way to shift some of those responsibilities … or to figure out a way to recruit more people.”
