These laws ostensibly regulate private transfers, but in the fine print are aimed directly at hindering the creation of new gun owners and otherwise trapping us in flypaper, by criminalizing the lending and renting of guns even under supervision. The Washington state officials say they won't enforce that part of the law, but....
Next up are Nevada and Oregon, last time I heard about this.
The chaos agent in me was hoping that 591 would pass alongside 594, to see how the state would have to reconcile directly conflicting bills. Sadly, 591 was massively outspent.
I am hopeful that, eventually, for-cost registration schemes will eventually go the way of the dodo, as I personally equate them to a poll tax, so either the laws will be rescinded on those grounds, or FFL fees will be eliminated, which should ameliorate at least some of the issue.
I'm a long way from Washington. Is the current interpretation of I594 being applied to temporary transfers? I'm in Maryland, and we have a similar transfer limitation, but were at least able to press the AG into issuing a formal opinion on some aspects of the law, though the specifics of it currently elude me.
But of course each state's enforcement will be different, and subject to change. The really nasty states didn't start out enforcing their laws in truly nasty ways until the zeitgeist changed enough and laws aimed for blacks and disfavored immigrants were applied to all but the anointed.
