"A former Marine involuntarily detained for psychiatric evaluation for posting strident anti-government messages on Facebook has received an outpouring of support from people who say authorities are trampling on his First Amendment rights," AP reports.

According to AP:

Brandon J. Raub, 26, has been in custody since FBI, Secret Service agents and police in Virginia's Chesterfield County questioned him Thursday evening about what they said were ominous posts talking about a coming revolution. In one message earlier this month according to authorities, Raub wrote: "Sharpen my axe; I'm here to sever heads."

Police -- acting under a state law that allows emergency, temporary psychiatric commitments upon the recommendation of a mental health professional -- took Raub to the John Randolph Medical Center in Hopewell. He was not charged with any crime.

The Rutherford Institute has "dispatched one of its attorneys to the hospital to represent Raub at a hearing Monday," says AP. "A judge ordered Raub detained for another month, Rutherford executive director John Whitehead said."

"For government officials to not only arrest Brandon Raub for doing nothing more than exercising his First Amendment rights but to actually force him to undergo psychological evaluations and detain him against his will goes against every constitutional principle this country was founded upon," Whitehead said.
