Hard to say whether it was justified, hence the investigation which would be standard in these circumstances.

I don't, personally, think he died as a result of this though.

He died three weeks later, he was 93 and had dementia. I know that in dementia, even the transition can kill them.

Using a baton, well he may have lunged at them. He did have another leg! There's a lot of circumstances we just do not know.

Just because he was 93, had dementia and only one leg doesn't mean he was incapable of inflicting extreme harm.
