Capitol Police - . It answers to Congress, not the President of the United States

The United States Capitol Police (USCP) is a federal law enforcement agency in the United States charged with protecting the United States Congress within the District of Columbia and throughout the United States and its territories. It answers to Congress, not the President of the United States, and is the only full-service federal law enforcement agency responsible to the legislative branch of the federal government of the United States.

Where Was the Intelligence?

While many details about how police responded to the events on the ground, which quickly morphed from a rally into a violent riot, remain unknown, both Swecker and Joyal agree that there appears to have been little in the way of intelligence gathering by law enforcement either using plainclothes officers in the crowd or even with regards to social media monitoring.

“If you’re pre-planning well, you are monitoring the social media sites that these groups use and this all happens on social media and I’ve had experience with this,” Swecker explains. “We also know that there are organizations that infiltrate and compromise a legitimate protest and I saw evidence of that. The FBI has intelligence on these groups, and I can’t imagine they didn’t pass it on.”
