''You look at the UK riots and you think, we don't ever want to go there, we don't ever want to see segments of our community saying they just don't care what the rest of the community does, they don't care for us, they have no engagement, don't recognise the legal system, don't recognise education. ''In the longer term the challenge for us is to fix that,'' he said. The police statistics show the rate of offending among the Sudanese community is 7109.1 per 100,000, while for Somali people it is 6141.8 per 100,000. The figure for the wider community is 1301.0 per 100,000. It is important to note that the overall proportion of crimes statewide committed by the Sudanese and Somali communities is only 0.92 per cent and 0.35 per cent respectively, and that people arrested and charged may falsely identify themselves as being from those communities. For both Sudanese and Somalis, assault offences are the most common type, constituting 29.5 per cent and 24.3 per cent of all offences respectively.

''Property is one of the issues, so they're stealing iPhones or money or things of value,'' Mr Cartwright said. ''But there's also a concerning trend of violence, violence that's not needed. So once they've got the property the violence continues. Maybe there's a thrill in it, maybe a bit of revenge, but it's coming out of a lot of groups, not just the Africans.'' Chief Commissioner Ken Lay and other senior police recently met members of the African community to discuss the crime statistics and ways to tackle the issue. One person present at the meeting, Abeselom Nega, said he shared some of Mr Cartwright's fears, and that the statistics presented by the police were ''confronting''. He said the violent offending was a serious concern to the African community, but that it was important to note the positive contribution many Africans made to the wider community. ''I don't have the experience that the Deputy Commissioner has, but prolonged disengagement and disenfranchisement would no doubt lead to social unrest,'' said Mr Nega, who heads iEmpower, an early intervention and diversionary youth service.

''Tackling crime on a daily basis is a reactive response, and the police would have to do that. But I think it is important to have a proactive strategy that addresses the root cause of disengagement. ''Far too many young people are out of school, not in training or employment, and this needs an immediate response from the government and the whole community,'' he said. ''But it is important to recognise that there are many young people making positive contributions to society, and that they are marginalised by the actions of those people who are responsible for the increase in crime.'' Mr Cartwright said it was crucial to recognise that police could not solve the problem simply by locking people up, and that the root causes of high crime rates needed to be tackled. ''The concern when you see these sorts of numbers is that, if you don't do anything about it, it will continue. We lock up all these offenders and there's another, growing tranche behind them who have the same issues,'' he said.
