Check this out; Code: A South Australian cop who chased a motorcyclist at high speed through a busy shopping precinct posed as much danger to the public as did his quarry, a court has heard. Prosecutors today said Constable Timothy Mark Hughes acted unreasonably during a chase that led to the death of Adam McNamara. Hughes' counsel, however, said police must sometimes break the law to uphold it â€“ and should not be under threat of prosecution for doing so. Hughes, 35, has pleaded not guilty, in the Elizabeth Magistrates Court, to driving in a dangerous manner. In November 2005, he charged Mr McNamara (a former police cadet) for riding his motorcycle without a licence. Two hours later, while driving an unmarked police car, he saw Mr McNamara on the road again. When he activated his lights and sirens, the motorcyclist sped away past Elizabeth City Centre. Hughes gave up pursuit just before Mr McNamara crashed fatally into a signpost. Today, prosecutor Leigh Simpson said Hughes drove through the 20km/h zone, in front of the centre, at 87km/h. He said police were only exempt from road laws when exercising "reasonable care". "Hughes was faced with nothing more than an offence of unlicensed driving," he said. "But he chose to accelerate considerably in the vicinity of a shopping centre. "If Mr McNamara had robbed a bank or murdered someone, the situation would be different. "The same risk to the public, posed by the motorcyclist, was posed by the police car." Joana Fuller, for Hughes, said Mr McNamara's driving justifed her client's "split-second" decision. "Mr McNamara posed a serious risk to the public, the sort of risk a police officer has a duty to stop," she said. She said it was the first time an officer had faced court for the lawful execution of their duty. "The verdict in this matter has wider ramifications than just consequences for Mr Hughes," she said. "Public safety could be compromised if police have their own concerns about being prosecuted. "Mr Hughes' situation is not a one-off â€“ the prosecution of other officers is pending, potentially, on this outcome." Magistrate Sue O'Connor will announce her verdict in December. I hope the copper gets a kick in the arse. Pursuits against motorbike riders need to be BANNED or engage a helicopter . Sure if its in pursuit of a murderer chase them and sit back and wait til he kills himself, but for mistermeaners and traffic violations come on. A bloke at Bathurst recently was chased by the zealous hwy patrol car and the motorbike rider crashed on a bend just out of town and died for what 'rolling through a stop sign'.
