This past week we've seen disturbing examples of gross teenage irresponsibility.
In California Friday, an 18-year-old girl streamed herself driving-drunk on Instagram.
The video continued as she crashed the car -- and went to check on her 14-year-old sister, who was thrown from the back seat and killed on impact. And in Florida - police investigated five teen boys who video-taped a man drowning in a lake near their house - and taunted him from the shore - instead of calling for help. Police said the teens' actions were horrifying but possibly not criminal.
Dr. Frances Jensen, a professor of neurology at the University of Pennsylvania and the co-author of The Teenage Brain: A Neuroscientist’s Survival Guide to Raising Adolescents and Young Adults, joined Jim to discuss whether there’s an explanation for the behavior.
