programs: Assault on authenticity" in "As seen on TV: Reality vs. fantasy in occupational portrayals on the small screen," Fall, 2003, Occupational Outlook Quarterly, Bureau of Labor Statistics, US Department of Labor, Washington, D.C., retrieved June 1, 2017 Another criticism of the show is the depiction of police procedure, which some consider to be decidedly lacking in realism. For instance, the show's characters not only investigate ("process") crime scenes, but they also conduct raids, engage in suspect pursuit and arrest, interrogate suspects, and solve cases, all of which falls under the responsibility of uniformed officers and detectives, not CSI personnel. Although "some" detectives are also registered CSIs, this is exceedingly rare in real life. It is considered an inappropriate and improbable practice to allow CSI personnel to be involved in detective work, as it would compromise the impartiality of scientific evidence and would be impracticably time-consuming. Additionally, it is inappropriate for the CSIs who process a crime scene to be involved in the examination and testing of any evidence collected from that scene. CSI shares this characteristic with the similar British drama series Silent Witness. However, not all law enforcement agencies have been as critical; many real CSI investigators have responded positively to the show's influence and enjoy their new reputation. In the UK, scenes of crime officers now commonly refer to themselves as CSIs. Some constabularies, such as those in Norfolk, have even gone so far as to change the name of their crime scene unit to "CSI". CSI recruitment and training programs have also seen an increase in applicants as a result of the show, with a wider range of people now interested in something previously regarded as a scientific backwater. CSI effect The "CSI effect" is the alleged phenomenon of CSI raising crime victims' and jury members' real-world expectations of forensic science, especially crime scene investigation and DNA testing. This is said to have changed the way that many trials are presented today, in that prosecutors are pressured to deliver more forensic evidence in court. Victims and their families are coming to expect instant answers from showcased techniques such as DNA analysis and fingerprinting, when actual forensic processing often takes days or weeks, with no guarantee of revealing a "smoking gun" for the prosecution's case. District attorneys state that the conviction rate has decreased in cases with little physical evidence, largely due to the influence of CSI
