The CSI effect

  • infotainment- a highly stylized, edited, and formatted form of entertainment that is disguised as informative or realistic, but in fault is not scientifically corrected

  • prosecution carries the burden of proving the defendant guilty "beyond a reasonable doubt”

    • some juries refuse to convict without definitive forensic evidence

    • CSI programs lead to a singular correct answer

  • reality- forensic conclusions are only as good as the technicians who retrieve the evidence, test, and conclude it

  • CSI problems show no concern with human error

  • Reality- numerous professionals have lied under oath, faked their credentials, and fabricated evidence

  • some think TV crime shows are real but they are not

  • CSI has a positive impact on forensics because finding resources and increases awareness for forensics

  • Empirical evidence: the information obtained through observation and documentation of certain behaviors and patterns through an experiment

    • defines attorned have the opportunity to suggest to the jury that fingerprints of DNA should be introduced

  • prosecutors have begun to use “negative witnesses” to explain why forensic evidence might be absent

  • voir dire- the preliminary examination of a witness or a juror to determine his/her competence to give or hear evidence

  • prosecution and defense and question the potential jury

-before the CSI effect

  • prosecutors rarely had to worry about making a sophisticated presentation or presenting some evidence in every case

    • prosecutors say these types of shows make it more difficult for them to win convictions, especially if scientific evidence is irrelevant or absent

defense attorneys and the CSI effect

  • defense attorneys have positive and negative opinions about the CSI effect

    • some defense attorneys say that jurors rely too heavily on scientific findings and are unwilling to accept that human or technical errors can compromise those finding

  • some defense attorneys embrace the CSI effect because their clients are being found “not guilty” due to insufficient evidence

impact on law enforcement

  • police departments and crime lis have spent much of their annual budgets to acquire modern technology and training

    • thousands of dollars are being spent on DNA technology or trance evidence collection

    • fingerprints are footwear evidence is being overlooked

    • departments believe they need to improve their forensic capabilities

    • there is more collection and booking of evidence

impact on crime labs

  • quantity of evidence being sent to the labs is increasing at an enormous ate

    • police expect miracles from crime lavs

    • police are now sending more samples to be analysed

  • as samples increase, so does the backlog of the crime lab

    • for example, the crime lab in Westchester NY handles nearly 1,000 DNA tests, which is up from 400 just 5 years ago

impact on education

  • 350% increase in the number of programs featuring forensic sciences as a course of study in colleges and universities

influence on the criminal mind

  • The CSI effect may be altering how crimes are committed

    • increases in criminal cases in which suspects burn or tamper with evidence

  • certain views use these shows as training grounds on how to cover up their own tracks


myth- crime labs do not lie

reality- there are sample degrades, tests are inconclusive, and lab technicians make mistakes

myth- some of the science in the state- of - the- are and can only be performed by real lab technicians

reality- many techniques on the shows do not exist conceptually, meaning they have not been invented


overcoming the CSI effect in law enforcement

  • refreshing training- conduct frequent training to explain what is and is not needed with regard to reservations, documentation, and collection efforts

  • caseholds- departemnt should look at the demographic serves and determine training and technology-based upon case hold

  • incoming the public- educate the citizens of the realities of forensic science

  • dedicated personnel- hire educated and trained personnel who have a background in forensic investigation
