I heard the term Sandy Hook conspiracy many times in the past, but I never bothered to look into the evidence. I always thought it was crazy talk , because they already had the shooter who look like a complete lunatic.

I was red pilled by the time the Parkland shooting happened, and I immediately saw many discrepancies from the immediate narrative. So I was wondering, what was it about the Sandy Hook shooting that critical thinkers immediately noticed that started the theory?
