The Federal Bureau of Investigation has been under increased scrutiny in recent years due to a string of flawed testimonies and evidentiary submissions. According to The Atlantic, the forensic techniques used have been subjective and resulted in a staggering number of wrongful convictions. One can only imagine that if the FBI is guilty of such misdeeds, local crime labs may be subject to suspicion, too. There are four common issues that can occur in crime labs and compromise the reliability of their evidence.
Submission of subjective evidence
This article notes that submission of subjective evidence has been a contributing factor in a number of false convictions. Indeed, some crime labs have presented items such as bite marks and hair as objective evidence, when in fact, they are still subject to interpretation. This pattern-based form of evidence can be manipulated easily and as such should not be treated as an objective finding.
Human error and sloppy work
Perhaps the most disheartening of all issues in crime labs is the prevalence of sloppy work and errors that compromise the objectivity of the lab's findings and often put defendants at risk. Many studies have revealed that lab associates may be susceptible to making mistakes and submitting incorrect results for a variety of reasons. No matter what the cause is, however, the result is an innocent person's life on the line.
Deliberate misrepresentation and bias
Even worse than sloppy lab work is the possibility of deliberately sabotaged results. Lab workers may have access to information about a case they are testing for, and in such situations, prejudice may motivate them to report false results. Racism, sexism and other pernicious issues in the criminal justice system are likely to contribute to this. In such cases, the defendant may have little recourse in proving the compromise of the lab work.
Financial compensation for convictions
Another of the recently revealed motivations for incorrect results is the financial incentive many labs enjoy for results that garner a conviction. In other words, labs can receive bonuses if they report results that are submitted as evidence against a defendant. This reward quite obviously compromises objectivity, and the accused are left vulnerable to the consequences of corruption.
There are many factors that influence the results submitted by a lab, but it is clear that they are not always reliable. If you are facing charges and concerned about protecting your rights, hiring an attorney can help you navigate these and other issues you may encounter.
