Frontline is een Amerikaanse docu serie van de zender PBS. De serie ging in première op 17 januari 1983.
Sinds de start in 1983 heeft Frontline documentaires over openbare aangelegenheden uitgezonden die een breed scala aan complexe menselijke ervaringen onderzoeken. Het doel van Frontline is om de impact van de documentaire verder te laten gaan dan de oorspronkelijke uitzending door als katalysator voor verandering te dienen.
In the aftermath of the Sandy Hook tragedy, President Obama called for a national conversation about guns in America. Nowhere is that conversation more intense than in Newtown, where FRONTLINE and The Hartford Courant find a town divided and explore how those closest to the tragedy are now wrestling with our nation’s gun culture and laws. In the wake of the mass killings at Sandy Hook Elementary School, FRONTLINE investigates a young man and the town he changed forever. Adam Lanza left behind a trail of death and destruction, but little else. He left no known friends, no diary. He destroyed his computer and any evidence it might have provided. His motives, and his life, remain largely a mystery. In collaboration with The Hartford Courant, FRONTLINE looks for answers to the central–and so far elusive–question: who was Adam Lanza?
