The Police, FBI and Secret Service recently surrounded the home of Brandon Raub. 

They asked him questions at his front door. He was immediately arrested and brought to John Randolph Metal Hospital.  An early report was he was arrested for injuring a local policeman. Then, he was said to be making threats which were terrorists in nature. Later, the FBI said he was not arrested.

He has a Facebook page promoting political action against the establishment by attending the Richmond Liberty March.

Brandon is a decorated Marine. 

Everything but the initial confrontation is on video tape. Here is the perfectly calm man being taken to his car.

It is likely the government will stick to the mental illness story; it works for Putin. 

So, as you consider closing your Facebook account, considering the concept devised by the Supreme Court: events that have a chilling affect on free speech. That meant something back in the day.
