Seven members of a US militia have gone on trial accused of plotting to wage war against the US.
It is alleged the Hutaree group planned to kill a police officer then attack the funeral, in an attempt to trigger a revolt against the government.
Members of the Michigan-based militia are accused of sedition, or rebellion, and weapons offences.
But they say they were just exercising their constitutional right to free speech, assembly and to bear arms.
Nine militia members were arrested in March 2010 in southern Michigan, Ohio and Indiana, as a result of an undercover operation involving a group informant.
Law enforcement officers allegedly seized machine guns, unregistered firearms and parts for improvised explosive devices.
According to the indictment, the group planned to target state and federal police officers, referring to them as "foot soldiers" of the government and participants in a "New World Order".
The prosecution is said to have about 100 hours of video and audio recordings of the group allegedly talking about police.
In the tapes, David Stone, 47, the alleged ringleader, is quoted as saying: "I think we got to just start hunting them here pretty soon.
"They're easy to find, they're sitting alongside the road and they got these red and blue lights on top of their car."
A website in the name of the Hutaree group described them as Christian warriors and showed video footage of military-style training exercises.
Assistant US Attorney Christopher Graveline said: "The court will hear testimony and examine evidence concerning this particular group's hatred for, and desire to do physical harm to, law enforcement."
But the accused deny being homegrown extremists and say it was all harmless bluster.
Mr Stone's wife and co-defendant, Tina Mae Stone, told the Associated Press news agency: "It was just a bunch of good old boys out to have fun. We did survival stuff. I did it mostly to spend time with my husband."
The other defendants are David Brian Stone Jr; Joshua Stone of Lenawee County, Michigan; Thomas Piatek of Whiting, Indiana; Kristopher Sickles of Sandusky, Ohio; and Michael Meeks of Manchester, Michigan.
One of the accused, Joshua Clough of Blissfield, Michigan, reached a plea deal and another, Jacob Ward of Huron, Ohio will be tried separately.
All of those arrested were released on bail, despite prosecutors' objections, with the exception of Mr Stone Snr.
