Looks like the Parkland shooter was special needs and was denied...
"But Mr. Cruz was legally an adult, and he wanted to graduate from Stoneman Douglas, according to a new report released late Friday by the Broward County Public Schools. A Cross Creek staffer gave him three options: transfer to the school, sue the school district, or stay at Stoneman Douglas — without any of the special-needs assistance he had relied on since he’d been found to be developmentally delayed at age 3.
The options, the school district’s new report found, were insufficient: Mr. Cruz by law and district policy should have been able to remain at Stoneman Douglas with special-needs protections. He didn’t know that but chose to stay anyway, no longer receiving any help or accommodations. It was Nov. 3, 2016."
