Question

                                           C 

              Crime-fighdng technology is getting more sophisticated(高级的) and rightly so. The police need to be equipped for the 21st century. In Britain we ve already got the world's biggest DNA database. By next year,the state will have access to the genetic(基因的) data of 4. 25 million people: one British-based person in 14.Hundreds of thousands of those on the database will never have been charged with a crime.

              Britain is also reported to have more than four million CCTV (closed circuit television) cameras.

There's a continuing debate about the effectiveness of CCTV. Some evidence suggests that it's helpfiil in reducing shoplifting and car crime.It has also been used to successfully identify(识别)terrorists and murderers. However,many claim that better lighting is just as effective when it comes to preventing crime, and that cameras could displace (转移) crime. A police report said that only one crime was solved for every l,000 cameras in London in 2007. In short,there's conflicting evidence about the effectiveness of cameras,so it's   likely that the debate will continue.

              Professor Mike Press,who has spent the past decade studying how design can contribute to crime reduction,said that,in order for CCTV to have any effect,it must be used in a targeted way.

Most cameras that simply record city centres continually — often not being watched 一 do not produce results. CCTV can also have the opposite effect of that intended,by giving citizens a false sense of safety and encouraging them to be careless with property(财产) and personal safety.

              Professor Press said:“All the evidence suggests that CCTV alone makes no positive influence on crime reduction and prevention at all. The weight of evidence would suggest' the investment is more or less a waste of money unless you have lots of other things in place.”He believes that much of the increase is driven by the marketing efforts of safety companies who promote the crime-reducing benefits of their products. He described it as a “lazy approach to crime prevention" and said that authorities should instead be focusing on how to change the environment to reduce crime.
