"Specially trained" officers would have been deployed to serve an arrest warrant if police knew the family at the remote property was paranoid and dangerous, a coroner has heard.

Constables Matthew Arnold and Rachel McCrow were shot dead in an ambush at Wieambilla, west of Brisbane, while seeking to arrest Nathaniel Train, who had also been reported missing in NSW.
