You have probably seen those TV shows where police and crime scene investigators use forensic science to reveal and catch the culprits of a crime. You have seen how authorities brought criminal masterminds to justice, even after they tried to hide their crimes. You have read in newspapers how authorities have used DNA evidence to convict suspects of violent crimes.
However, it may surprise you that the justice system also uses forensic evidence to overturn convictions and acquit suspects. It’s not as popular as CSI, but the Innocence Project shows that forensic evidence goes both ways: it can convict and acquit.
Below are some ways defense attorneys use forensic evidence to defend their clients.
Challenging the evidence
Lawyers can question improper evidence collection and analysis. Errors and contamination can cast doubt on the evidence’s reliability. The Innocence Project has shown that improper forensic science led to wrongful convictions in 53% of the 251 reversals it has attained.
Disproving eyewitness misidentification
Recent evidence shows approximately 70% of wrongful convictions resulted from eyewitness misidentification. People can have faulty memories, implicit biases and even facial blindness. Wrongful convictions can result from mistakenly identifying the wrong person. Research shows that DNA evidence is more reliable than witness testimonies, prompting reforms in the criminal justice system.
How it can help you
If you are accused of a violent crime and want to prove your innocence, consider turning to forensic evidence to help establish your case. Remember, though, that forensic evidence is only one of the tools used in a criminal trial. Authorities can also use audio and video recordings, phone and travel records, and other evidence to convict or acquit you. Consult with a legal professional to help you explore how forensic evidence may be used effectively in your defense strategy.
