You have not given us a credible link.
So? It is wikipedia, wikipedia is not a governing document.
The capitol police operate under laws, that congress writes. I do not see those laws on your wikipedia page, how come.
Wikipedia is not a document that would be used in a court of law, an inquiry by congress.
The Capitol Police have a chain of command, can you provide us with the Operating Procedure that states what that chain of command is, routinely, and in the case of an emergency.
Does the Capitol Police operate under the CFR? Why have you not once referenced the CFR? Are you unaware that there is are laws, codes, regulations, which you will not find on wikipedia?
wikipedia can be a great place to start a search, and on some topics it is great. But wikipedia falls very short, to the point of being propaganda.
It is nice you can go to wikipedia to confirm your opinion, that does not make you right, nor wikipedia accurate.
Who does the Capitol Police board answer to, report to, during an emergency?
