There are several fairly simple, effective ways to eliminate school shootings, however the gun grabbers refuse to even contemplate them, Why?  Because stopping school shootings is the opposite of their goal - their goal is to ban all forms of firearms.  Dead children are their only effective means to do this.
The question they always ask is "How many dead children will it take for you to give up your guns?  And THAT is exactly what they mean , they won't entertain ANY means of reducing the deaths , except ZERO firearms in private hands.

They aren't against guns per say, just they want them in the hands of people they control.
