Last February, Stuart Chaifetz sent his ten-year-old son Akian to school wired with a hidden recording device to investigate reports about the boy's behavior.

Aikan, who has autism, returned home with a tape containing hours of shocking verbal and emotional abuse from his teachers, the content of which has made national headlines.

On Thursday afternoon, Chaifetz held a press conference to announce that his son's school district had reached out to him personally and promised a thorough review of what happened. Chaifetz said that he's decided to hold off on releasing more audio from the recordings but that he'll make more content public if he doesn't believe that the school's authorities are doing their best to bring justice to his son's case.

Today on Starting Point, Chaifetz calls the school's decision to investigate a "vindication and a victory" and reiterates his threat to release more video if the issue isn't properly addressed.

There's a new debate building about the cause of autism, fueled by new numbers from a CDC report showing a significant increase in the number of kids diagnosed with autism spectrum disorder.

The numbers are staggering: The latest report shows diagnoses are up 80% in the past decade. In 2000 and 2003, about one in 150 children were diagnosed with autism. The latest data suggests 1 in 88 children have autism.

Is there a real cause for concern here that the threat of autism is growing? Or are the diagnoses criteria becoming broader?

This morning on "Starting Point" Austim Speaks's chief scientific officer Geraldine Dawson, Ph.D. talks about the new study. She's joined by Glen Finland, author of "Next Stop" which chronicles her experience raising her son David, who has autism.
