How Reliable is DNA Testing in Forensic

Forensic investigators rely to a larger extent on the DNA information collected from a crime scene to enhance their investigations or provide concrete evidence that will close their case, however, the use of DNA information as evidence is marred with series of issues that question the reliability of the process of collecting the highly susceptible DNA where a slight mistake can lead to a wrong prosecution, therefore, admissibility of DNA results as evidence of a crime in a court of law is seriously considered to ensure all procedures were followed correctly and DNA tests were conducted by a reliable DNA test lab. Therefore, if ever accused of a crime where DNA test is being used as evidence consider hiring a reliable and experienced criminal defense attorney who can assist you in challenging the DNA tests, the attorney, however, must be familiar with DNA cases, collecting and testing procedure to successfully exploit possible loopholes that questions the reliability of DNA testimony in a court of law. Although the use of DNA tests as evidence continues to become popular because of its matched ability to identify criminals, DNA cases are highly susceptible to errors, this article has outlined some common sources of these errors so keep reading this article.

One of the reasons why DNA evidence is complex to pursue in a court of law is because of the sensitive DNA collection procedure which involves a good number of people such as police, forensic team, witness, and forensic support staff, with such a team it is almost impossible to prove that the DNA was not damaged, contaminated or destroyed during its collection given that it is a highly delicate molecule.

Given that DNA evidence is mainly collected from semen, blood stains, dead skin, hair, etc is not easy to prove in a courtroom that the amount collected was enough to provide reliable evidence that is admissible in court, a criminal defense attorney can ask for evidence that ensured the DNA was not compromised or destroyed by exposure to sunlight or cold, police may also be required to prove that the DNA was from the guilty party because it can be from an innocent person can be at the crime scene and the DNA used against the individual, all these possibilities make it challenging to use DNA as evidence in crime scene because they are possibilities of forensic investigators and the team getting it wrong even when they are careful with the whole process.

Human beings have over 99.9 percent DNA similarity with 0.1 percent being distinct to a specific individual, this makes it challenging for the forensic team to use DNA collected from a small sample in a crime scene which may be compromised or damaged as evidence, however, with modern technology reliability of finding the distinct 0.1 percent DNA from a small sample has seen DNA evidence becoming more and more admissible in courtroom. Those are some factors that questions the reliability of DNA evidence.
