There is not one single protection that a "hate crimes" law would grant that is not already in place. Murder, rape, assault, arson and other crimes are already illegal.
Texas did not need a hate crimes law to execute one of the men who murdered James Byrd, and put another on death row. Indiana does not need a hate crimes law to execute someone for committing a bias-motivated murder.
What a hate crimes law would do is punish thoughts.
