I am concerned that if these mass shootings keep happening there Will Be More Anti-Gun Laws.
The pro-gun people including Republicans and GOP Candidates must come up with a plan to stop these shooting or keep the victims from being shot.
Getting Rid of Gun-Free Zones and permitting people like this latest batch of Defenseless Victims to be able to defend themselves by being armed would be a good place to start.
And putting mental cases who are mentally ill enough that they can not live among others without wanting to kill someone in the Hospital where they belong.
Even if firearms were totally impossible to obtain, anyone who really wants to hurt and kill people can do it by multiple means including explosives or something as readily available as a Car or Truck.
I hope this ends up being an attack by ISIS etc.
