It is also vital to keep a simple strategic concept in mind.
“You cannot win just by playing defense.”
A lot of such oppressive laws are passed gradually, keeping up continual pressure. The only proper response is not only to prevent such gradualism, but to push in the opposite direction, putting the advocates of oppressive laws on the defense.
Look at the current anti-gun schemes, with an idea of not just blocking them, but of reversing them.
1) Define ammo components as an unhealthy threat. This is being pushed through by government agencies, mostly EPA and Interior, so the only possible response is the threat of reducing the power and scope of these agencies.
2) Tax it if it shoots. In this case, taxation, directly or indirectly, of a Civil Right, such as newspapers, is very questionable, and in past has been left up to the states. However, there can be push back here with the idea that the federal courts should disallow taxation of Civil Rights, to include the purchase, ownership or use of guns.
3) Engineer the practicality out of it. This again goes to federal agencies who must be reduced in size and authority. In this case the Consumer Product Safety Commission and the Center for Disease Control. However a lot of this is also taking place at the state level, so it needs to be fought there as well, likely through the federal courts again.
4) Excessive tracking measures for guns and ammo. This is probably the most tangible threat, and is just the tip of the iceberg to the massive federal push for personal dossiers and surveillance of all persons. Data mining of such information is a powerful tool to get control over the Civil Rights of the citizenry.
Unfortunately, there is yet to arise potent opposition to this monumental encroachment of freedom, liberty and privacy.
5) Shut down guns shows to kill private sales. Efforts to control gun transactions is backdoor registration, by forcing the association of individuals to guns. Government is already pretty blatant about forcing gun dealers to retain records for government use, to evade restrictions on their directly keeping records. The best way to fight back about this would be to require “sunset laws” on keeping information about gun sales by private and corporate dealers.
6) Call in the lawyers and bankrupt a gun owner. Not just gun owners, but gun dealers, and even gun manufacturers are a target for barratry by unscrupulous anti-gun lawyers working for anti-gun organizations. This is a tough nut to crack, as for many years the courts have been amenable to litigious scoundrels. But it needs to be done.
7) Call in the United Nations to grab small arms. The UN is a festering boil. Even with numerous PhDs representing western nations, the average education among delegates in the general assembly is 5th grade. The best way to take it down, or at least to reduce its mischief, would be to not directly call for its dissolution, or that the US should leave it, but that its headquarters should be moved to some place more *entertaining*, like Beijing.
Suggest that such a movement should be every 50 years in future. This would solve so many problems.
Margaret Thatcher called that the "wratchet effect". The government slides to the left with the lefties are in power (Obamacare, for instance) and when the righties get power they do not reverse what was done but simply stop, but usually slow down, the slide to the left.
So, there is a real fear that Obamacare and Dodd-Frank will only be repealed in part, or heaven forbid, not at all.
I suspect a lot of courts and bureacracies are going to use this as a means to barring a lot of folks from accessing firearms.
