Improved security behind dropping crime rate
Tougher sentencing（更严厉的惩罚） is less of a deterrent to property crime than increased security, according to an Australian Institute of Criminology survey of those who would know best.

According to the institute, between 2001 and 2009 motor vehicle theft 机动车辆盗窃 declined by 57 per cent, burglary 入门盗窃 declined by 49 per cent and other theft fell by 32 per cent.
Data in subsequent years接下来一些年里 could not be used, the AIC said, because definitions and counting rules changed.
To get to the bottom of the decline降到最低, the AIC interviewed 994 police detainees 被拘留者 at Brisbane and Southport in Queensland, Bankstown and Parramatta in New South Wales, Footscray in Victoria, Adelaide in South Australia, East Perth in Western Australia and Darwin in the Northern Territory in 2012.
All were asked: “Can you think of any reasons why property crime has decreased over the last 10 years?”
Of the 470 who answered the question, the most frequent answer最常见的答案 was注意积累犯罪率下降的原因： improved security (31 per cent), changes to policing (20 per cent), increased affluence (11 per cent) and increased imprisonment (10 per cent).
The AIC admitted the study had some shortcomings, such as the fact 36 per cent of respondents were aged 15 or under at the start of the reference period, so “might not reasonably be expected to be able to explain the reduction”.
Still, the AIC said its findings could offer an insight into 提供一些灼见 property theft trends.
“The fact that improvements in security were identified more often than any other reason for the property crime drop may be significant given that there is relatively little research that has explored this factor and even less that has focused on Australia,” the AIC found.
“Similarly, little has been written about how changes in policing have contributed to the property crime drop.
“This suggests that both of these factors warrant further investigation.”
But ultimately the AIC conceded the study may not be that conclusive.
“It is important to note that by focusing solely on 只关注police detainees it is unclear whether the reasons given for the property crime drop are any different to those one would expect from a sample of the general population,” the report stated.
“The assumption made here is that by being closer to offending behaviour, police detainees would generate more plausible hypotheses, although this is an assumption that may warrant further testing.”
