A few years back, we posted some research someone had done noting that youth violence had decreased drastically over the years as violent video games became more popular. Now Digg is highlighting a similar, and rather dramatic, drop in overall violent crime during the period since 1993 (when the video game Doom was released). Obviously, this is a correlation, not proving any kind of causal linkage. However, if it were true that these video games were convincing people to go out and commit actual crimes, it would be hard to bring that into line with this data. Combined with recent studies that have shown that violent crime decreases when violent movies are released, it certainly suggests that the "threat" of such movies and video games aren't as big as some would have you believe.
