Too bad Google doesn’t have billions and billions of dollars in assets that she could sue them for.
Why sue Google? (besides “sue deep pockets and they’ll pay you just to go away”.) I’m sure there’s plenty of legal disclaimers a la “this information is not guaranteed accurate; Google is not liable for errors; use at your own risk.”
Google Maps et al exist for getting people pretty, but not perfectly, accurately from point A to B.
If your purpose is to go to a location and DESTROY IT, you’d d@mn well better KNOW you’re at the right address. Hire a surveyor if there’s any doubt. The demolition company is to blame, not Google.
Google should just write her a check for double the value of her home. Chump change for them but scads of good press.
