From what I've read, this IS extreme negligence and should be prosecuted as such. It's not about gun laws.So knowingly purchasing a firearm for a mentally troubled 15-year-old, giving it to him for Christmas, and not confiscating it when school authorities present evidence of intent to kill in advance a mass shooting is not against the law? If that isn't extreme negligence enabling or in this case fostering a mass murder, then we have a lot of work to do to build common sense into our gun laws.
