Because one of the main sources of our national unity is our belief in equal justice, we need to make sure Americans of all races and backgrounds have confidence in the system that provides justice. In America we must make doubly sure no person is held to account for a crime he or she did not commit--so we are dramatically expanding the use of DNA evidence to prevent wrongful conviction. Soon I will send to Congress a proposal to fund special training for defense counsel in capital cases, because people on trial for their lives must have competent lawyers by their side.
