A new study says gun violence in PG-13 movies has tripled. Researchers say they counted the number of times a character carried a gun with the intent to harm or kill in the top thirty grossing movies each year since 1950.

Media critic Jeff McCall says the stats can be misleading.

"It's not just the violence but how it's portrayed and I think that's what we should be concerned about, more than just the amount."

Professor McCall says it's not the violence, it's the story. But he doesn't trust movie producers.

"They're just putting it in there because it's easier to just display on the screen than to write a complex plot that might make sense."

Pop culture Professor Bob Thompson says there's no way for Hollywood to ignore gun violence.

"I think we're seeing a lot of gun violence in movies because gun violence has become so much a part of who we are and what happens in the United States of America."

Thompson says he's not sure there's a link between movie violence and mass shootings in real life. And he says it would be foolish to just cut violence willy-nilly.

"If we say that violence and gun violence is intrinsically bad and shouldn't be in any of these movies or stories we start eliminating some real masterpieces."

For example, the classic "High Noon" is loaded with gun violence, but none of it is considered gratuitous.
