Frank Larkin’s commitment to America is remarkable. A former Navy SEAL, he served in the Secret Service, at the Pentagon and as sergeant-at-arms of the U.S. Senate. However, as correspondent Scott Pelley reports, Larkin’s most significant contribution may be what he’s done since his son, Ryan, took his own life. Ryan was, like his father, a decorated Navy SEAL, and his death by suicide was attributed to depression. But Frank Larkin did not accept this explanation, and when pathologists discovered Ryan suffered from scarring in his brain, likely due to repeated low-level blast exposure, this father campaigned for a change in how Special Operations and the rest of the military train and protect their service members. When wildfires tore through the Pacific Palisades and Altadena neighborhoods of Los Angeles this winter, 9 billion pounds of toxic ash and debris were left behind.

Correspondent Sharyn Alfonsi goes behind the scenes with the Environmental Protection Agency as it completes the first step: removing the hazardous waste. The rest of the debris is in the hands of the Army Corps of Engineers. Despite expedited cleanup efforts, some residents say they still don’t feel safe returning home.
