Dallas DNA
Dallas DNA is an American TV show that first aired on the Investigation Discovery cable channel on April 28, 2009. It shows how the Dallas County, Texas District Attorney's Office has worked with several law school programs that help people who aren't guilty. There is now a new division called the Conviction Integrity Unit that re-examines past convictions where DNA testing could either clear or strengthen the convictions of people who are now in Texas prisons because of them.
