He was acting oddly prior, too. Not that anybody cared.
“stares at wall in deep thought, eyes closed, appears to be resting [but] not asleep.”
What’s odd about that? I always stare with my eyes closed...
His behavior is “normal” for a prisoner with all considered.
Just as his behavior was equally ‘normal’ given his life and losses. He CHOOSE to act on and plan his assault on the school kids. I give him no room other than choosing to become the ‘criminal minded’ individual he opted for.
