The event did actually happen. The theory that it didn't happen at all is a cover for the actual meat and potatoes. Adam Lanza, the supposed shooter, never existed. You can look up family lineage online, and his parents are shown to have only ever had one child, Ryan Lanza. His parents also have gone under several different aliases, common for intelligence assets. The shooting happened, those kids did die, but it wasn't at the hands of "Adam Lanza" (who conveniently only has one low quality picture in existence). It was likely done by one of the alphabet agencies.
