1. The FBI would not send in a SWAT team to break up a protest on private property. 2. An FBI SWAT team member, or any trained police officer, would not hit a protester over the head with a baton, even if assaulted. That's considered deadly force, and would, in all likelihood, result in a serious head injury or death. It's the equivalent of shooting a suspect in the use of force scale. This show needs a law enforcement liaison, because there are implausible things in every episode.
