All of the stories from Sandy Hook on the morning of the shooting said it was done with multiple handguns. Later in the day they said they found a rifle in the car, and later again they said that everyone was shot with a rifle. Immediately after that, Feinstein introduced her rifle confiscation bill.
I have never seen four handguns morph into a rifle.
I am also curious how the police determined that Lanza shot his mother, despite the fact that there was no evidence linking him to her shooting, and the fact that she was shot with a .22 – which Lanza did not have.
