Newtown victim's dad: 'I'm Jesse's voice'

Neil Heslin testified at a Senate Judiciary Committee hearing on the proposed assault weapons ban Wednesday. His son Jesse was murdered in the Sandy Hook school shooting along with 19 other children. Anderson Cooper spoke with Mr. Heslin about his loss and the gun law changes he believes will make school safer.

"I just feel that it's something I have to do...I feel there's got to be changes made," Heslin said about his decision to speak to lawmakers. Despite the difficulty of  being exposed to the political tension over gun control during a time of mourning, he believes he would be letting his son down if he didn't testify.
