Why not file a police report for the theft of 400k USD?
This was not in one of the cities that allegedly isn't prosecuting crimes anymore, and was before any of that or the defund movement or what have you, and I'm in a red state. I suspect the people who complain about that stuff as if it's new and caused by recent action have just never interacted with the police before—I have plenty of other examples of their not caring to do any amount of investigation of crimes against individuals, too, no matter what evidence is already at hand, going back decades. And zero examples of their actually investigating anything.
This kind of nuisance report you're suggesting wouldn't go anywhere.
