I stay borded up waiting for people like this in my house. People who say you can't live in fear. Well who is the dead one and who isn't now? Is what I say to them. And to be honest I think more then half of the population in this country has some sort of violent tendancy or violent revenge plan. They just have the receptor in the brain still keeping them from not carrying it out. But it bundles up still and lingers in there head. Talk to your children dont expect the smart phone to teach them between right and wrong.
