The perfect storm and the other side has learned its lessons.
They knew that our side would wait and allow the families to grieve. They were waving the bloody shirts before the bodies were cold.
They had teenagers, not elementary school kids, to be the(ir) voice(s).
They need something to flog the R's with for the Midterms. Trump-hate, Russia, Tax-cuts, etc. are all loser issues for them. They need something.
And yes, the Sheriff, School (board), and FBI need to demonize someone else to keep the spotlight off their failures and misdeeds. Who better then the NRA ??
We got caught flat footed.
