Wrongful Convictions: Exonerated by DNA Since 1992, 333 people in the United States have been wrongfully convicted and exonerated by DNA testing. Of these 333 people, 20 served time under death row. (Inn Proj) Because of this, faith in the criminal justice system is at times questioned. 1. What causes wrongful conviction? 2. Something about organizations such as innocence project… 3. How does DNA prove innocence? 4. What is life like for those after exoneration and release? What Causes Wrongful Conviction? There are six major issues that may result in a wrongful conviction. The biggest contributing factor is false identifications or eye witness misidentifications. This affects more than seventy percent of convictions that later result…show more content…
Junk science is unproven data that is presented as fact. Hair analysis is one example of how forensic science can be used to falsely incriminate an individual. Hair analysis is compares the consistencies between two or more hairs. This science is able to eliminate suspects, but not positively identify them. Another example along the same lines would be blood type. A suspect with the same blood type as evidence does not make a person guilty, but if the suspect had a type O blood and the evidence was type B it clearly was not that particular suspect. These two examples are still used in cases to help persuade the guilt of a…show more content…
Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell. Retrieving this amount of data is both exhausting and time consuming. A short cut has been found that scientist use to analyze smaller segments of DNA. Short tandem repeats (STR) are segments of DNA sequences that are repeated. (BIO) The span of each STR differs from one person to the next. The STR length contrast is what is used to differentiate individuals. Gel electrophoresis then uses the STRs to create a DNA profile. The gel electrophoresis separates the STRs depending on their length and the pattern is then shown in fluorescent gel creating the profile. These profiles are then used by scientist to compare patterns between evidence and or suspects to determine a match or not a match. The probability of two people having the same amount of repeated sequences in STRs is one in billions of
