Las Vegas killers were 'anti-police'

A married couple who shot dead two officers and a bystander in Las Vegas acted out of hatred for the police and the government, authorities say.

Suspects Jerad Miller, 31, and wife Amanda Miller, 22, who died at the scene, viewed law enforcement as "oppressors", said police.

Officers are investigating whether they were at Cliven Bundy's Nevada ranch during a stand-off earlier this year.

The couple left a swastika and a "Don't tread on me" flag on the dead officers.
