I think this depends very much on your state, if not individual community. (And this is a personal opinion, not legal advice.)
In Arizona in the last several years, the Tucson prosecutor has taken a very draconian view of self defense in deference to Arizona state laws, making it difficult on honest homeowners who arm then protect themselves, including filing assault and attempted murder charges against the home owners. (NRA has even gotten involved) 100 miles to the north, It's just the opposite: people defending their homes (and following state laws) often get exonerated in a week or less.
As such, IMHO, if you were in Tucson, you are more likely to have your otherwise-lawful-gun collection taken, (lawfully or otherwise) than in the Phoenix area.
Does that help any?
