Effetto CSI

[Malandrina]

Non so quanti di voi seguano CSI. Io ero appassionata della serie principale, ora ogni tanto do un'occhiata a CSI Las Vegas e NY.
Cazzeggiando su Wikipedia, mi è saltato fuori questo, in cui in breve si parla del potenziale effetto che questo tipo di tv show avrebbe sui giurati di processi reali e sui criminali.

Mi chiedo però come sia possibile farsi influenzare da un telefilm in cui quelli della scientifica arrivano sulla scena del crimine con le fluenti capigliature al vento, senza nemmeno le soprascarpe e in cui in qualsiasi luogo siano riescono SEMPRE a trovare il capello/unghia/cellula epiteliale dell'assassino. Se per caso la Scientifica dovesse esaminare la mia macchina ci troverebbe di tutto di più, altro che IL singolo capello.

Fra l'altro, non so come funzioni negli Stati Uniti, ma mi sembra improbabile che gli uomini della Scientifica interroghino i sospettati. Non è compito della polizia?

CSI effect

The CSI effect (sometimes referred to as the CSI syndrome) is a reference to the phenomenon of popular television shows such as the CSI franchise raising crime victims' and jury members', even criminals', real-world expectations of forensic science, especially crime scene investigation and DNA testing.[1] Much of these concerns stem from the "dramatic license" taken by the writers of forensic science television--glamorizing the field, overstating the accuracy of forensic techniques, and exaggerating the abilities of forensic science--and from the extension of pop images past the realm of entertainment programming and into that of news reporting and the general criminological dialogue.[2][3] The CSI effect is purported to skew public perceptions of real-world forensic science, as well as the behavior of criminal justice system actors; this is of particular concern in the courtroom setting, where many prosecutors feel pressured to deliver more forensic evidence.[4][5]

Manifestations of the CSI effect

Influence on jurors

Although speculation as to the validity of the CSI effect abounds,[6] researchers have only recently begun studying the effect of CSI on juror behavior.[7] One empirical study of the CSI effect suggests that viewers of CSI and other forensic science shows are more critical of forensic science testimony and less persuaded by it; however, these same differences were not found for viewers of Law & Order (and other "general crime" shows), which implies that the CSI effect is limited to those who watch specifically forensic-science shows.[1] Another study surveyed potential jurors and failed to find a link between CSI viewing and whether the jurors would "demand scientific evidence" in order for them to convict a defendant.[5] A third study examined mock jurors' impressions of a criminal trial and found that CSI viewers' verdicts were not significantly different from non-viewers.[2]

People who overestimate the reality basis of shows such as CSI: Crime Scene Investigation and its spin-offs may develop unreasonable expectations of actual forensic practitioners. Although the technologies lauded on these fictional programs are found in real crime labs, they often require much more time and deliver answers more equivocal in real life than on television. Analysts worry that people will come to believe that real criminalist science has become as swift and certain as we have always wished justice to be. DNA evidence in particular is expected more and more by jurors whether it is relevant or not in a given case. Some potential jurors find themselves, during voir dire, being asked whether they are viewers of shows such as CSI.

Influence on the criminal mind
The CSI effect may also be altering how crimes are committed. Tammy Klein, a criminalist for the Los Angeles County Sheriff's Department, and other criminal experts have noticed an increase in criminal cases in which suspects burn or tamper with evidence (e.g. using bleach to destroy DNA evidence), or attempt to carefully clean the crime scene of trace evidence such as hairs and clothing fibers. For example, critics cite a particular murder case in Trumbull County, Ohio. The prime suspect in this case, described as a CSI fan, murdered a mother and daughter. He then used bleach to wash his hands of blood and covered the interior of his car with blankets to avoid transferring blood as he transported the corpses, which he then burned along with his clothes and cigarette butts (which he feared would yield trace amounts of his DNA). He attempted to throw the remaining evidence into a local lake, including the murder weapon, a crowbar, but was unable to dispose of the evidence due to the lake's surface being frozen. The surviving evidence was later recovered by investigators and the suspect arrested.[8]

A more optimistic view of the CSI effect would suggest that these programs send criminals the message that no matter how much they try to cover up their crimes, forensic scientists can track them down. (As the character Delko said on the February 6, 2006 episode of the CSI: Miami spinoff, "Criminals only clear away what they can see.") Criminals who try to clean up a scene risk leaving evidence of the clean-up itself which may be traced back to them. Other crime shows (Diagnosis Murder, for instance) feature episodes in which doctors and police themselves use the access they have to information to commit crimes in ways that are difficult to detect. Indeed, even a century before DNA evidence came into prominence, Arthur Conan Doyle's Sherlock Holmes once remarked, "When a doctor does go wrong he is the first of criminals."[9]


Influence on forensic science training programs
Academia is also said to feel this effect. Universities have seen an increase in students enrolling in forensic science and related science programs. There has been criticism from police departments that, in an effort to increase their student numbers, universities have been offering unsuitable courses, leaving graduates unprepared for real-world forensic work.[10] The traditional academic route followed by a would-be forensic scientist has been to pursue a primary (bachelor's) degree in a general-science subject such as chemistry or biology, followed by a suitable postgraduate course or some type of in-service training. In 2003, the American Academy of Forensic Sciences promulgated accreditation standards for forensic science educational programs through its Forensic Science Educational Program Accreditation Commission (FEPAC),[11] based on recommendations from the US National Institute of Justice.[12]

Highly publicized trials such as those of Scott Peterson, Robert Blake and O.J. Simpson have also drawn many people into forensics. TV networks like Court TV, Discovery Channel and A&E also carry many programs depicting forensic investigations of actual cases, such as Forensic Files, Cold Case Files, Body Of Evidence: From the Case Files of Dayle Hinman, The New Detectives, and American Justice, as well as other fictional series such as Cold Case and Cold Squad.

Bravo. Mi raccomando, portati anche la torcia da 20.000 watt, da usare anche in pieno giorno. Nel mio bagaglio non manca mai...
