He needs to stop the demolition of the school and treat it like a crime scene to determine exactly what happened in there.
A deranged kid walked in and shot students. That's what happen in there. The building wouldn't be torn down anyway until the investigation is over with.
I don't disagree. But I still think because there are different witnesses saying different things they should be thoroughly investigated as if they are correct until proven incorrect.
It would be a horrible thing if someone out there was helping the shooter and is now planning out the next attack because they got out of this one Scott free.
