Sen. Christopher Murphy D-Conn. gave an emotional speech during Sen. Dianne Feinstein’s press conference introducing a new bill that would ban so-called assault weapons.

Murphy insisted that if an assault weapons ban had been in place, many of the children shot at Sandy Hook “would be alive today.”

He also blamed video games for influencing the Sandy Hook shooter Adam Lanza.

“I think there’s a question as to whether he would have driven in his mother’s car in the first place if he didn’t have access to a weapon that he saw in video games that gave him a false sense of courage about what he could do that day.”

Lanza reportedly played Call of Duty – the popular series of first-person shooter video games.
