The deadly California bar shooting has many in our country asking why.
At least 12 people died after a gunman opened fire into a southern California country bar similar to the ones that line Broadway.
Professor of Psychology Nancy Durham worked at Pepperdine University for 30 years before teaching at Lipscomb University. One of the victims killed in the shooting attended Pepperdine.
Durham said the increase of mass shootings can cause people to become desensitized.
"We do become sensitized and we take in information both at a cognitive and a subconscious level and the level of emotionality that I felt at Columbine you can't sustain that," she said.
Durham said there are several factors that can cause a person to cause senseless violence and people should not be quick to blame the shooter.
"We know when people watch violence on the media whether it be video games they're involved in, or television programs or movies, that overtime they becomes desensitized to the aggression and even sometimes will become more aggressive themselves," she said.
She said the decisions some make should not cause others to walk in fear.
