My first instinct is to say that this is retarded and reflects poorly of our society.
But I like to see the video if that exists and reserve judgement.
IF this is another FRIVOLOUS lawsuit then I would PENALIZE the granny AND the lawyer!!
It's important to PENALIZE the lawyer or else they have NO SKIN in this game. Bottom feeders!
As soon as you can define "frivolous" to stand up to the requirements of law, then you can do this. Usually, the judge will determine this in pre-trial, so you don't really need such a law. It's what judges are for.
