Interesting. Prior to that I thought that Fox is the least likely to be a pharma shill, out of all the major media companies in the US. For those who are interested, here's a list of Hannity's advertisers. Among them are companies such as Bayer, Pfizer and "America's Biopharmaceutical Companies".

But it also needs to be said, that the actual reason why there are so many lunatics who are ready to shoot up any venue or school, stems from family and society. Children who grow up without fathers or with abusive parents are much more likely to do such terrible things. So my guess is, that (in most cases) the drugs are the trigger, and not the actual reason for this behavior.
