Taking the attorney's version of events at face value, the cops have egg on their face and dirt on their hands here. I question the legality of deployment and use of a taser, gun, or any other control device if a suspect has not been placed under arrest and is compliant.According to Las Vegas police policy, police can use deadly force based on the severity of the crime, whether the suspect is a threat to the officer or others and whether the suspect is actively resisting arrest or attempting to avoid arrest by fleeing.
Of course, that is just the lawyer's version. If the cops involved ever agree to the same story, maybe their version will trump his. It may come down to who is the best creative writer.
