Leon Panetta, a former US Defense Secretary and CIA chief, told the BBC that police would take no chances following January’s attack.
“We have got to have constant intelligence on domestic terrorists, have to track their possible efforts to again repeat what happened on January sixth and I think that’s what you’re seeing now, is an abundance of caution to make sure that we are properly prepared to react, if in fact any group attempts any kind of armed attack again on the United States Capitol,” he said.
There are dozens of militias across the US with varying ideologies, but generally they are anti- government. While they don’t necessarily advocate violence, often they are armed and some have engaged in violent demonstrations.
Many say they are acting in self-defense over fears of what they believe to be increasing federal government intrusion, with gun control a particular concern.
