The most important advance was DNA testing. Many people that were in prison were found to be innocent when the evidence against them was dna tested. Unfortunately the evidence was not available for all people so it is a fact that many innocent people are in a cage still. One of our founding fathers said that it was better for 10 guilty men to go free than 1 innocent man to go to jail.
