This is never more evident that when hoaxers stumble their way through the Sandy Hook DNA Evidence. Sandy Hook hoaxers have even suggested that if shooter had been captured, he could not have been convicted.
The DNA evidence was clear. The shooter's clothing and weapons were splattered with DNA from victims caused by the close range shooting. Lanza's DNA was also present on the weapons.
Every bullet casing matched the rifle, therefore we know the Bushmaster AR-15 fired the rounds inside the school. The rifle also that bore his DNA and was kept in his bedroom. Not to mention the fact the shooter was there, geared up up with weapons, and ammunition, with a years long obsession with mass murder; having just murdered his mother while she slept in her bed.
The shooter's conviction is a no-brainer.
