Jim, there's certainly that. Also, they won't be able the chant the "in the home" mantra that we are so used to hearing.
Those parts of HI handgun law are toast. They will absolutely have to allow handguns in the home. They will have to allow for (handgun and ammunition) transport to and from gun ranges.
The permitting process will have to be changed, to allow for challenges to denials.
Actually, barring the "outside the doorstep" meme, a whole slew of changes will have to be made.
They can fall back of issues of Standing, but that will only take them so far. The real issue is carry for self defense and the plaintiff has made no bones about that. It's either a protected right or it isn't.
