The dealers want to cover their butts, plain and simple. When people don't know what they can do, they don't do anything.You are right in that most LE officers don't give a crap. It's a federal thing , so local PD thinks " Let DOJ worry about it". I've told an officer I was buying an AR and keeping it out of state and he said,"Why, unless you are doing something stupid (Speeding, bragging, dealing drugs, contract killing, etc.)who's going to know if you own it? Take it to the range and shoot it." I think the only time DOJ will check shooting ranges is at large events (3 gun matches). Even then, the range can tell them, "I don't want you harrassing my patrons." It's alot easier if you're a private club though. Being open to the public, you are "supposed" to let LE do what they have to do.
