Mass shootings in America: Northeastern criminologists James Alan Fox, Monica J. DeLateur in Homicide Studies refute common myths about mass murder.
It is explaining a new study that debunks the idea that mass murder has been increasing. There were several articles released after Newtown that manipulated statistics to show an increase when none existed.
Here is the study ---->
Mass Shootings in America: Moving Beyond Newtown
It addresses each of these myths and debunks them individually:
* Myth: Mass Murderers Snap and Kill Indiscriminately
* Myth: Mass Shootings Are on the Rise
* Myth: Recent Mass Murders Involve Record-Setting Body Counts
* Myth: Violent Entertainment, Especially Video Games, Are Causally Linked to Mass Murder
* Myth: Greater Attention and Response to the Telltale Warning Signs Will Allow Us to Identify Would-Be Mass Killers Before They Act
* Myth: Widening the Availability of Mental Health Services Will Allow Unstable Individuals to Get the Treatment They Need and Avert Mass Murders
* Myth: Enhanced Background Checks Will Keep Dangerous Weapons Out of the Hands of These Madmen
* Myth: Restoring the Federal Ban on Assault Weapons Will Prevent These Horrible Crimes
* Myth: Expanding “Right to Carry” Provisions Will Deter Mass Killers or at Least Stop Them in Their Tracks and Reduce the Body Counts
* Myth: Increasing Physical Security in Schools and Other Places Will Prevent Mass Murder
* Myth: Having Armed Guards at Every School Will Serve to Protect Students From an Active Shooter and Provide a Deterrent as Well
