New Orleans attacker tried to use high explosive that could have killed hundreds

The New Orleans truck attacker built two bombs using what investigators believe was an explosive so powerful that they could have sprayed shrapnel hundreds of yards and potentially killed or wounded hundreds of people. 

The bombs did not detonate on New Year’s Day. But experts say the devices Shamsud-Din Jabbar built with a compound believed to be RDX would have had devastating effects were it not for an amateurish blunder.
