The only power government has is the power to crack down on criminals.
Well, when there aren't enough criminals, one makes them.
One declares so many things to be a crime
that it becomes impossible for men to live without breaking laws." - Ayn Rand
Here is the basic problem. The anti-freedom, government-control playbook has -- for a very, very long time -- written an entire web of laws designed to be able to arbitrarily make any person a federal felon. It isn't just guns, it now permeates every aspect of our lives, from the environment, to taxes, to financial affairs. We're perpetually expanding police and prosecutorial power, a process only occasionally slowed by the courts. This also includes the increasing leeway with which prosecutors can enforce broadly written federal conspiracy, racketeering, and money laundering laws. The federal criminal code has become so vast and open to interpretation, that a U.S. Attorney can find a way to charge just about anyone with violating federal law. In fact, it's nearly impossible for some business owners to comply with one federal regulation without violating another one. We're no longer governed by laws, we're governed by the whims of lawyers.
Trying to decide if someone is an unlicensed gun dealer or not has been left deliberately vague. That way, if they want to swoop in with a 3:00 am "shock and awe" SWAT raid with the news media in tow, they can quite arbitrarily decide to make an example of YOU while leaving the next guy who bought/sold 20X the number of guns you did entirely untouched.
Basically, they want everyone to fear the gray areas, as well as live in dread and fear being the guy whose neighbors see the guns piled up in the front yard, the house completely trashed, and the news media trumpeting the words "arsenal" and "weapons cache".
It is all about intimidation and control. The argument in these last couple of pages illustrate the point. Some people are going argue for and behave in an overly scrupulous manner, and try to convince everyone of the correctness of their position because coming to the attention of a US ADA is a life-altering event. Other people argue, that isn't what the statute says.
Forget about the whole "# angels on the head of a pin" dissection of the issue, because it still doesn't address the core. The bottom line is every person's propensity for risk in the trade-off between liberty and security ends up meaning everyone draws the line in a different spot for them.
An interesting read would be: Three Felonies a Day: How the Feds Target the Innocent.
An excerpt from the book description:
The average professional in this country wakes up in the morning, goes to work, comes home, eats dinner, and then goes to sleep, unaware that he or she has likely committed several federal crimes that day. Why? The answer lies in the very nature of modern federal criminal laws, which have not only exploded in number, but, along with countless regulatory provisions, have also become impossibly broad and vague. In Three Felonies a Day, Harvey A. Silverglate reveals how the federal criminal justice system has become dangerously disconnected from common law traditions of due process and fair notice of the law's expectations, enabling prosecutors to pin arguable federal crimes on any one of us, for even the most seemingly innocuous behavior. The dangers spelled out in Three Felonies a Day do not apply solely to ''white collar criminals", state and local politicians, and professionals. No social class or profession is safe from this troubling form of social control by the executive branch, and nothing less than the continued functioning and integrity of our constitutional democracy hang in the balance.
