I'm still confused on a lot of the ins and outs of these bills. Can someone explain to me why one or many firearms that were purchased by me and/or my wife can't be considered OUR firearms? She and I can BOTH own a particular vehicle. Is the only reason we can't BOTH own a particular firearm simply the fact that we don't register/title firearms?

Not that I'm looking for titling or registration... just curious is all.
