In an interview in W magazine, John Travolta blames therapeutic drugs and psychological counseling for the "recent school shootings." As everyone knows, Mr. Travolta is an expert in the field of psychiatry and pharmacology.
One can only assume Travolta would be speaking of the murders at Virginia Tech. In this situation, the shooter would have greatly benefited from more psychological counseling and perhaps a prescription or two that would have helped him to control his behavior. It is sad that this did not happen.
This is just an exercise in passing the buck. Blame the gun, the drugs (or lack of them), or whatever else you want. It is the actions of the individual that caused the result.
