Not clear why the homeowner wouldn't want to address this the simplest way possible -- namely making a claim on its homeowner's insurance policy.
"Is the local law enforcement liable or driver of vehicle?"
Not clear how we can possibly know the answer to this from here, given we weren't there and don't have all the relevant info. One presumes that law enforcement wasn't doing anything wrong. :) The damage would need to be in the six figures I'd bother pursuing a public government entity for wrongdoing even if I had proof that the officer had engaged in wrongdoing, however, when I can be otherwise compensated through my homeowner's policy.
