how many children have to die before we limit access to firearms?

in a few short days, we have seen a homeless person go into a school, sexually abuse children, and then murder them, then there was the angry young man who went into the school and killed those in his path to pay back the bullies, and then we have the man who entered a school and bound young women and executed them, picking and choosing which could leave and which would stay, and leaving notes for wife and children apologizing,....but his killings were about a 20 year old vendetta.

I don't mean to simplify any of those situations, because they were much more complex than i have stated, but they all speak to the ease that weapons can be accessed....

it makes me ill.
I worry about my grandchildren going into school and being confronted by the gun toting crazy...about the girls being assaulted, the boys being harassed, and any of them just snapping and .........

i know all the arguments on both sides about gun control. BUT SOMETHING MUST BE DONE...
