Yes, we can be mad at dealers because not fighting this is counterproductive to their very existence. Any dealer unwilling to piss in this broad's face in court should just sell all their shit and give it up, right now- because if they don't fight this (fight either legally in court or legislatively, by demanding the legislature produce a bill which strips the AG of firearm regulatory powers) means the AG can screw over even obedient dealers that have been obeying the actual law for a long assed time.
I am guessing, however, at this stage some of them (like FS) are stopping sales as a matter of pragmatism; I predict either two things are going to happen.... in a month or less there will be a legal throatpunch against the AGs office over this; (or a "retraction" once this birdbrain gets told that she doesn't have the lawful authority to do this) or it's going to be allowed to stand which will result in lots of fun chaos and mayhem as everyone becomes a felon and stops giving a shit- because if thats the path chosen it pretty much means "you will own guns and take huge legal risks whether you wanted to or not" or "you don't own guns at all". There is no middle ground anymore if the AG isn't forced to respect the law.
