The list may be unofficial or completely fabricated, but the fact is they are going to do it sometime soon. Just waiting for the time.
They need a really high-profile shooting with a stereotyped gun on the list. You can take that to the bank. It IS coming.

When the time comes, then sound the alarm. Until that time, why don't you drama queens knock off the high school hystrionics.
