Yes, Curtis Morrison should have the right to a DNA test to prove his innocence. If a DNA test can exonerate someone who has been wrongly convicted, there should never be a reason to deny the test be performed on the evidence. In the interest of justice, Morrison is entitled to the DNA test.
In a fair and just society, Curtis Morrison should have the right to have DNA tests performed to prove his innocence. Morrison has sought testing since 2006. He believes he is innocent of his murder charge because two men entered the crime scene. Testing was not available at the time of the crime. Morrison would have to have DNA testing results entered as new evidence. Judges in California approved DNA testing in other cases in the Court of Appeals. However, there is too much evidence against Morrison. Morrison would have to show that testing could prove his verdict wrong.
If it helps to prove that he is not guilty as he says he is then he should have the right to have anything tested to prove so. Many people get angry with someone accused for murder, but what's worse is the possibility to be angry at the wrong person convicted.
Although the evidence in questions is over 40 years old, it should be tested. If someone is in prison because there was no way to test this kind of evidence at the time, it is an injustice to not test and possibly keep an innocent man in prison for a crime that may be proved to have been committed by someone else.
