We’ve rounded up every major piece of evidence we could find that leads theorists to say the “official narrative” of events “doesn’t add up” and provided the facts that show why these questions can be easily explained. We’ve ignored the empty accusations with no evidence to support them (it was the Jews!) and focused only on the theories that try to present actual empirical or circumstantial evidence.

Let us know if we missed any and we’ll add to it as more myths emerge. In no particular order, here is your comprehensive guide to disproving the Sandy Hook Truthers:

Why aren’t the adults sadder?  “They aren’t behaving the way human beings would act,” as conspiracy theorist Jay Weidner told fellow conspiracy theorist Jeff Rense on his radio show. Theorists have zeroed in on Robbie Parker, who they say wasn’t grieving hard enough for his slain 6-year-old daughter, Emilie. In one widely circulated clip, Parker laughs before stepping up to the microphone, and apparently someone says “read from the card” (as in cue card) before Parker breathes heavily in anticipation of beginning a press conference. “This is what actors do to get into character,” one popular YouTube video states. Rense and Weidner also take issue with the mourning of the school nurse, the family of slain teacher Victoria Soto, and others. “ALL ACTORS??? NO TEARS,” wonders the author of SandyHookHoax.com on a page featuring videos with numerous interviews from the shooting.

Answer: People mourn in many different ways, sometimes all at once. As a recent Scientific American article on gref noted, “oscillation between sadness and mirth repeated itself in study after study … Time and again, a grief-stricken person’s expression would change from dejection to laughter and back.” George Bonanno, a psychologist at Columbia University who studies grief, even developed a way to determine if this mourner’s laughter was genuine or merely a facade to hide grief — he determined that they “exhibited the real thing.” Scientists think this is part of our internal resilience mechanisms kicking in, because constant grief is simply too much for a person to handle.

What about Emilie? One of the most common myths circulated on message boards and in YouTube videos is that Emilie Parker is actually alive. The “proof” is a photo purportedly showing her with President Obama when he visited the school after the shooting. Conspiracists know it’s Emilie because she’s wearing the same dress as the one Emilie wore in a family portrait taken before the shooting (an alternative theory is that the girl in the photo with Obama is her “double”). Other websites take issue with the family portrait, alleging it was Photoshopped for some reason, pointing to the fact that the Emilie is making a “devil’s horns” sign with her hands and “making the devil’s horn hand sign isn’t easy. Try it yourself. Imagine getting a 3- and 4-year-old do it.”

Answer: The girl on Obama’s lap is Emilie’s little sister. It’s amazing that we have to say this, but sometimes younger siblings wear clothes passed down to them from older siblings, and sometimes siblings look alike because they are siblings. And there’s no evidence or even motive given for why the portrait would be Photoshopped. Making a “devil’s horn” gesture is actually incredibly easy. Try it yourself.

Why do they all look the same? Numerous websites juxtapose pictures of people from Newtown against pictures of similar looking people from Aurora, Colo., and assert they are the same actors.

Answer: Not all women with brown hair are the same person.

But what about the rifle? Alleged shooter Adam Lanza used a Bushmaster AR-15 assault rifle as his primary weapon, but conspiracist have seized on footage of police removing a long gun from the trunk of Lanza’s car. “This reveals the ‘Big Lie’ of the mainstream media … the Bushmaster AR-15 rifle was left in Lanza’s car,” conspiracy website NaturalNews states in a story picked up by Alex Jones’ InfoWars this week.

Answer: Actually, the gun shown being removed from Lanza’s car was a shotgun he never used. Lanza brought three guns inside the school — the AR-15 and two handguns — all of which were found inside the school.

How come the memorial pages were created before the shooting? One of the most cited pieces of “hard evidence” in the hoax theory is that memorial pages for the victims were allegedly created before the shooting even took place. Theorists point to Google results giving dates before the shooting for various pages.

Answer: Actually, this is a very common glitch for constricted-date Google searches. The results are imprecise and can often display incorrect dates on the search page, even when the date on the actual page is correct when you click through to it.  For instance, here’s a Fox News story on the Sandy Hook shooting that Google says is from Oct. 1, 1983 — how come Fox News didn’t stop the shooting if it had 30 years advance notice???

What about the car? Early on, theorists latched on to the notion that the black Honda Accord driven by Lanza was not actually owned by his mother, as police say, but by a man named Chris Rodia, who was mentioned on a police scanner at the time of the shooting. One theory is that Rodia may have been an additional shooter. An even more advanced theory is that Rodia may have been taking advantage of mentally ill people like Lanza and using drugs to make them do his bidding.

Answer: This one was debunked by the theorists themselves just a few days after the shooting. Blogger Joe Quinn obtained the police audio, which definitively debunking the myth. (Rodia appeared on the scanner because he was getting pulled over in a traffic stop miles away, but his license plate doesn’t match Lanza’s car). “This was a huge blow, because lots of people were making big leaps on this … but we now have to look elsewhere,” another amateur investigator said on YouTube.
