Electro-shock therapy has it's place in treating SOME patients with extreme depression or other mental disorders. It's effective for some patients, not all, and no one knows why.

Autism, to the best of my knowledge, doesn't fall into the category treatable by shock therapy.

Per the article:
The school’s parents’ association also issued a statement lauding Tuesday’s ruling. “We are grateful for the careful deliberation and the decision reached by the court and these judges,” they said. “We have and will continue to fight to keep our loved ones safe and alive and to retain access to this life saving treatment of last resort.”

The parents said they favored electric shocks over physical restraints or medication.

“There is no other treatment for our loved ones, and we will not stand by as they are mechanically or chemically restrained,” they said.

These people need to be held accountable. The parents, too.
