SA govt says police will quell shootings NEW powers will help police curb a spike in gun violence that has South Australia's top cop frustrated, the state attorney-general says. There have been 13 incidents since New Year's Eve, the latest involving a man who was shot dead at a shopping centre in the city's north on Sunday. After Sunday's shooting, Police Commissioner Gary Burns said the rise in gun-related incidents was an "enormous concern." Most incidents have involved shots being fired at buildings or other property although one other man has been killed and two people injured. Attorney-General John Rau said in most cases there was some relationship between the people firing the guns and their intended targets. "In some instances those relationships might be personal ... in others it's because they are involved in some ways in criminal activity," Mr Rau told ABC radio on Monday. He said he had every confidence in the police and their ability to curb the violence, especially given the range of new laws at their disposal. Those new provisions include offering bigger sentence reductions to people who provide information on fellow offenders, greater use of metal detectors around pubs and clubs and provisions to prosecute people who inadvertently help a crime gang. "The police now have tools they did not previously have and I am very confident they will use them," Mr Rau said. Mr Burns said on Sunday investigations into some recent shootings had been hamstrung by victims refusing to cooperate. Police investigating the latest shooting were continuing to examine closed circuit video footage from local businesses in the area while a post mortem examination on the victim was due on Monday.
