If Sandy Hook shooting is a hoax, no others could do it except the Feds because so many resources were activated: police, media, government officials and informants (some were called as "actors" by people.) And they of course would let out disinformation to meddle the water.
Here is a doctored picture. Madeline and Samantha have no legs in the photo.
And they deliberately let Madeline wearing Emilie's dress in photo with Obama. At the purpose to confusing people then to prove the suspicious people are "conspiracy theorist". Remember, no others have the motive and resource to do that. Those who could take pictures of Obama and Samantha have the privilege or that photo was a product of the "strategy office"(disinformation office) too.

That picture was created particularly to mislead people to conclude Emily hadn't died. (they let Madeline wear Emily's dress) That's a trap set up for suspicious people. It proves even the president could be obedient actor to be manipulated by the perpetrator. See how happy those actors are. Are they family members who just lost a lovely girl and after memory service, or it was a celebrating party?
