This is so fucked up wrong in so many ways, and I should know as I lived with my Gran from when I was a baby until she died a couple of years ago.
If I could, I would so give the parents seven shades of asskicking for doing what they did to that poor woman, not only that, but the kids should be ashamed as well for having no respect for the lady, and as for the police, it's obvious that they're all a bunch of fucktards; especially the Chief of Police for arresting this poor old lady...
I've a feeling this family are going to be the most hated family in the USA after this incident, if they aren't already the most hated family in the USA...
