I don't know the guy other than he's a long time member of the vintage mustang site and it seems his government is failing him. His car was stolen and found but law enforcement won't go get it.
I’m not sure how it works in California but in Florida Leo’s wouldn’t be able to enter the property without a warrant. A warrant is drafted and approved from probable cause. I suspect there isn’t enough probable cause to get a warrant and that’s why no one is doing anything.
