President Obama,
There is one important issue that is not being covered and seems to be ignored by the mass media, that issue is psychiatric medications and their effects and side effects of their users and the link between the recent mass shootings. It is simply indisputable that most perpetrators of school shootings and similar mass murders of our modern era were either on or just recently coming off psychiatric medications. Here is a list of people.
Cho Seung-Hui Virginia Tech school shooting
Eric Harris from the Columbine school shooting
Patrick Purdy from the Stockton school shooting
Kip Kinkel Springfield School shooting
Michael Carneal Heath High School shooting
Jeff Weise
Joseph Wesbecker
Kurt Danysh
John Hinckley
Andrea Yates
Christopher Pittman
This needs to be investigated.
