Teacher Arnie Reyes was the only person who survived when the crazed gunman entered his classroom. Reyes spoke to "GMA" this morning in an agonizing interview. He blames the police for not storming the building sooner. Teachers around the USA are now taking matters into their hands. They are going online for advice from other teachers on what they can do to keep their kids safe in the classroom in the event of the unthinkable.
