Easy, the same way there's a picture of all the kids that supposedly died with them all together in a group much older.

It was a big scam

All the homes around Sandy Hook were paid off the year before you could check on the county tax records.

Sandy Hook school was already closed before the incident even happened.

They demolished Sandy Hook after the falls flag to hide any evidence in the stop people from investigating it.

The truth will be out very soon especially with Alex Jones being sued over it.
All this information will come out during the discovery process.
