CBS/AP) LAS VEGAS - A couple spent hundreds of hours over four months plotting to abduct, torture and kill Las Vegas police officers as a way to attract attention to their anti-authority "sovereign citizens" movement, police said.

David Allen Brutsche and Devon Campbell Newman attended training sessions about sovereign citizen philosophy, shopped for guns, found a vacant house and rigged it to bind captives to cross beams during interrogation, and recorded videos to explain their actions and why officers had to die.

The movement they were intending to promote does not follow U.S. laws.

At every step, police said Thursday, an undercover officer was with them, documenting and recording the alleged plot.
