Brian Van Brunt, Ed.D. interviewed for story on "Some look to social media to monitor for signs of violent attacks"

Therapist, author, and incoming President of the National Behavioral Intervention Association, Brian Van Brunt, Ed.D. says many mass murderers leak their intentions, often online, to try to control the legacy of how an attack will be remembered.

"They're clearly writing, creating YouTube videos, there's dozens of cases," says Dr. Van Brunt. But how can it be detected? "There's some great technologies out there. We have listening platforms that are really a more suped up version of Google Alert," says Van Brunt.
