The man accused of shooting and injuring a ranger and a police officer in Nevada County is back in his cell after a court appearance. 

Brent Cole, 60, is being linked to the group called Sovereign Citizens Movement that some say encourages acts of violence against law enforcement.

Cole is charged with two counts of attempted murder and two counts of assault with a deadly weapon upon a peace officer. He's postponed entering a plea until his next court date on July 10.

Members of of the Sovereign Citizens Movement say they don't believe they have to follow the laws enforced by judges, officers and lawyers. They say they don't believe in paying taxes either. 

Other self-proclaimed members of the group have recently been making headlines.

Three weeks ago, a man and woman connected to the Sovereign Citizens Movement shot and killed two Las Vegas police officers while they were eating lunch, then shot a man in a Wal-Mart before being killed in a shootout with police.

A man in Georgia earlier this month -- linked to the same group -- crashed his SUV onto the steps of the Forsyth County Courthouse, tossing smoke and pepper spray grenades and shooting a deputy in the leg before officers shot and killed him.
