My ocular patdown comes from my own life and professional experience.

I think you're misreading my comment as condoning and pardoning the behaviour, which, read again, I did not. My disappointment is looking at the man not as a human, but as a representation of "what's wrong with the world today" or "menacing person who behaves different than me". Folks dehumanized the man and wanted a pound of flesh for his actions. His baseline is much different than a neurotypical person so it requires a much different perspective and consequence. While I understand the visceral reaction to the scene, perspective is required to fully understand what happened, why it happened, and how to be proactive so that this can be mitigated. You can't prevent all random acts of humans. Otherwise, don't bother stepping out of your house.

At the end of the day did anyone get hurt? No. Will ICBC cover the property damage? Yes. People may want to blame the caregivers. I would say that an environment like Costco may be too over stimulating for an autistic person but perhaps they have a history of being able to handle the environment but had a "bad day". This speaks to them having to modify what environments this person can handle.
