what about stolen smart guns?
do they need to be registered?
No, if they are smart guns, they are smart enough to register themselves!
I'll bet that this registry is about as accurate as the NFA registry. Do you think that the Boston cops, after taking a gun from a gangbanger, will bother to report it to ATF? Jack.
Knowing what I know wrt how PDs operate, my guess is that they probably don't spend much time looking for the rightful owners wrt guns, unless it is to jack them up on some charges. I've even seen some license plates in the PD's "lost & found", with no known attempt to contact the owner!
