Further Evidence Of Sandy Hook Hoax ???

Here is a video with evidence suggesting that the Sandy Hook Elementary School was not an operational school at the time of the "massacre":

So, why would there have been children in the building when Adam Lanza supposedly arrived with his weapons?

Very strange.

By the way, a common thread in several high-profile shootings/assassinations/bombings is the fact that multiple eyewitnesses report the presence of more than one shooter/bomber (and/or that the shooter/bomber had an accomplice), while the official government version of the event claims that only a "lone nut" was involved. This is the case for:

• JFK assassination
• Murrah Building bombing
• Aurora, CO theater shootings
• Sandy Hook school shootings
• Isla Vista drive-by shootings

Were all those eyewitnesses wrong, or did the FBI have a vested interest in disconnecting as many dots as possible in cases like this?
