There's a study out by The American Academy of Pediatrics about the rise in violence in PG-13 movies. As reported on Aljazeera America, today's PG–13 movies are more violent than R-rated movies.

The site quotes the study as saying gun violence in PG-13 movies has tripled since 1985, which is when that rating was created. Then one of the authors of the study says that the PG-13 rating is not adequately warning people of the harm that viewing these films might do. That's where I take issue with the study and that particular author; he says that just seeing a weapon makes a person more aggressive. The problem I have with that is that the number of violent crimes committed by juveniles has been decreasing steadily since the early 1990s. Same with gun violence. If movies have gotten more violent and just seeing guns makes people more violent, why aren't the numbers headed the other way? It's because people can tell the difference between movies and real life.
