Blaming Hollywood for giving ordinary citizens a much needed catharsis is like lowering the boom on restaurants for serving high cholesterol foods. With the first amendment on peoples' minds, the rush to censorship actually robs them of their freedom of choice and doesn't solve the problem. While certain 'unstable' personalities are always prone toward erratic behavior, posting warning labels on video games hardly addresses the more factual causes of violence. Many people may find sources of entertainment asthetically repugnant, but that doesn't mean they deserve censorship to protect the public interest. Moral sensibilities have to be distinguished from scientific facts linking various forms of 'entertainment' with violent behavior.
Adolescence is that esoteric twilight zone between childhood and adulthood.
Correlating recent tragedies with evidence of widespread escalation in violence among youth is without scientific foundation or even common sense. Throwing the book at misguided youths, trying them as adults, locking them up and throwing away the keys, doesn't begin to deal with the real causes of youth violence. Grandstanding with unrealistic research grants makes good photo-ops and publicity stunts and helps assuage some national pain but offers no real solutions. Hollywood isn't the one that needs a wake-up call, it's the White House for demonstrating the type of cosmetic superficiality which glosses over the relevant issues. Whether 'Hollywood' violence has any measurable impact on adolescent violence is anyone's guess.
