SAN FRANCISCO: Police in San Francisco defended their potential use of killer robots on Thursday, insisting they would be a "last resort" and only for very dangerous situations.

Detectives in the California city, where residents complain of a spike in crime, were granted permission this week to deploy machines capable of lethal force.
