Absolutely. I see every reason to keep a firearm off the books if possible. That said, I'd still not want to have a potential felony randomly lying around my house. And if I did (hypothetically) have unregistered firearms, i'd want every shot I could at making it difficult to prosecute me. If that means having a bunch of registered AW's (or serialized lowers, built from 80% or otherwise) around as "low hanging fruit" denyability (hypothetically) as "decoys" (hypothetically), so be it.
The Rifle on the Wall
"“[S]cientific proof” of both gun-rights and gun-control theories “is very hard to get”; therefore, requiring “some substantial scientific proof to show that a [firearm] law will indeed substantially reduce crime and injury” is tantamount to applying strict scrutiny to, and almost certainly will lead to invalidation of, the law." - Kamela Harris
