One of America's leading students of violence tells CNN that trying to prevent future massacres like the one at Newtown's Sandy Hook Elementary School should not be the driving force of America's policies to reduce violence.
"We can get misled if we focus on rampage killings like Newtown," says the man we've chosen for this week's CNN Profiles.
"To concentrate all of our violence reduction efforts on the most unpredictable, the hardest to control, the craziest incidents is, I think, a misallocation of resources," our guest tells us. He adds, "if we want to keep most people from being killed, it's the wrong place to obsess."
Who is this student of violence urging us not to "obsess" over Newtown when crafting our nation's violence reduction strategies?
His name is Steven Pinker, Professor of Psychology at Harvard.
