Whether a North-West man who stripped before punching  two ambulance officers acted intentionally has been central to lawyers’ closing arguments. Brady Christopher Oates has pleaded not guilty to two counts of assault, which stemmed from an incident at Circular Head on August 23, 2015. The crown argued Mr Oates’ actions were  intentional, while his lawyer  suggested pain medication administered in an ambulance caused the attacks.  There was little dispute about what actually happened. The Supreme Court, in Burnie, was told ambulance officers were called to an address at Forest, to find Mr Oates in pain from a dislocated shoulder, abusive and affected by alcohol. It was alleged Mr Oates was abusive to a female ambulance volunteer on the way to the Smithton District Hospital, and was given painkilling medication in the ambulance. At the hospital, the court heard, Mr Oates got off his bed, stripped, punched the volunteer and chased her around the room. Jurors  heard Mr Oates then punched a male intensive care paramedic, who restrained him until police arrived. Both ambulance personnel gave evidence during the trial. On Monday, crown prosecutor Jody Dennison told jurors the crown case was the pain relief administered through what he referred to as the “green whistle” did not contribute to Mr Oates’ “aggressive state”. Mr Dennison said he did not think jurors would have trouble finding Mr Oates was drunk, but the law said self-induced intoxication could not be used to excuse Mr Oates’ conduct. He said Mr Oates was in pain and drunk and angry as a result. He said he took it out on other people. Defence counsel Greg Richardson told jurors the presumption of innocence was the starting point of their deliberations. He said the prosecution had to prove beyond reasonable doubt Mr Oates intended to apply force. Mr Richardson said there was no doubt Mr Oates was affected by alcohol and acting inappropriately,  but the “behaviour that brings us here” came after the medication being administered. “If that isn’t a direct effect, this doesn’t make sense,” Mr Richardson said. “Someone should not be convicted for something they didn’t intend to do.”
