Eventually, it will stick. This may be the year. The gun-haters have been frustrated nationally over the inertia that has come over this issue. But in a long-standing Blue state like Wash., they can pull it off with virtually no political consequences. It won't surprise me if it passes this time around.They'll keep throwing this bubblegum at the wall until it sticks.
A couple of points in the law as proposed that bother me more than hardware issues.
1. The restrictions on where they may be used. There is room for interpretation as worded. There is plenty of room for law enforcement ignorance, once implemented. "Lawful outdoor recreational activity" of shooting on public lands might be very narrowly read. A ranger might say, "It says right here, while at a duly licensed firing range or while hunting; you're not doing either one of those, you're shooting in the woods." Which is a Class C Felony for violation, boys and girls.
2. The extremely limited right of transfer is very close to the taking of private property. The only way to transfer one of these firearms is to die. Many heirs concerned simply won't want to deal with this.
