I have a problem with the terrorism charge as well. They claimed all of the kids were in terror once the shooter started. Well, that is true of any robbery. I'm sure customers in a bank or store are terrified once a robbery begins. By that definition, every act of violence is a terrorism incident.
As for the parents, well I generally think charging parents is a slippery slope. I know my kids did things that I didn't find out about until years later. And I was the discipline guy in our house. But these people absolutely should be charged. This kid had problems, and they knew it. And they failed to lock up a gun from a 15 year old who was mentally unbalanced. No possible way I would leave a weapon available for my kids when they were that age.
I'm sorry if he was bullied, nobody deserves that, but I knew people who were bullied in school, and at times I was bullied. At no time did I ever think about blowing people away. And maybe he might have handled it better if his parents were more supportive. Maybe they needed to find another way of comforting him besides giving him a gun, and texting "Just don't get caught" when he was googling bullets in school. They knew he was about to go off. Clearly when the active shooter bulletin came out at his school, they both knew it was him. Maybe they needed to help him before this. As far as I am concerned, they should be given a maximum sentence. And hopefully the prison population will handle the rest.
And also the school authorities need to be put under the spotlight. They called the parents to the school, and when the parents left, they simply returned this deranged kid to the class. I spoke to a friend of mine who was a principal of a Catholic school for his entire life. His solution was to tell the parents they either take their son home and get him help, or he will call the police immediately and let them handle it. No way was that kid getting back into the class area. Totally crazy that people in charge of a school had the parents and the psycho kid in their office, and nobody checked his back pack and then they let him back into the school population. There should be some big time lawsuits coming out of this.
