Disagree with Jeff's claim that the link is largely political... although there is ALWAYS an element of that, there is a mountain of research around the topic, some pointing to a correlation or suggesting a causal relationship and others not... it is science after all :)
Google scholar has categorized a host of research in the area.
Link: Common sense in the debate about violent video games.
What more can you say, the link between aggression, crime, and violent video games is political at best, certainly not based on fact or logic. Link: TCS: Tech Central Station - Game Off?. These conclusions are corroborated by other strands...
Steve,
I reworked your query to remove television thereby focusing exclusively on research about video games, and added "youth". The search results went down pretty dramatically.
The research that the query returned was pretty sparse in the area of suggesting direct linkages, at best focusing on "subjects characteristically aggressive, such as men."
