Yeah, I agree with you on that. I think the article, and even the researchers, are utilizing a lot of word play between violence, aggression, vengeance, retribution, and anger. I think the study can be useful for showing that more research needs to be done in treating aggressive tendencies in people to make sure the proper methods are being used. However, I do not think it's anywhere near debunking conventional wisdom.

Adding the actual FDA link since it's not behind a paywall. Looks like they've looked at data going all the way back to 1973 to assess the efficacy and safety of the dosage. That will be an important bit of knowledge when the inevitable lawsuit comes out "because the FDA didn't do their due diligence."
