How reliably does animal torture predict a future mass shooter?
The Washington Post - 02/21/2018
Since the 1960s, some criminologists, psychiatrists and other investigators who study serial killers and mass murderers have claimed that animal cruelty is a possible predictor of future violence. But many children treat animals maliciously, even kill them, and a vanishing percentage become mass killers. In a study conducted with Jack Levin of Northeastern University, we found that 28 percent of 260 undergraduates admitted to having abused animals when they were children.
