Frontline has now posted preview and video trailer for two-part series next week on Sandy Hook mass killer Adam Lanza, how he was raised, the gun debate it set off locally and nationally--and portraying mother as "the 27th victim." Really? I would say "enabler" or even "accomplice," with her collection of guns, at the ready, which he took to school. Or perhaps I will change my mind after viewing series, which also looks at the gun debate set off by the tragedy. Here's trailer and excerpt.
