While I understand and respect that position, I just don't think the government should be mandating it. And I also do not find the lack of knowledge of the law to be persuasive. Citizens are always required to know the law. Ignorance of the law is never an excuse to criminal conduct. If we require and expect people to be knowledgeable and hold them accountable for knowing the law in every other area, why not for guns?
As for reciprocity, the question as posed was based on other states going to a constitutional carry system. The fact is that under the current state climate, many states are eliminating requirements. The current reciprocity setup as we know it may not last long. Additionally, it has been proposed several times in congress about providing for national reciprocity. Again, I think if the trend were to continue that direction, we wouldn't see the reduction you predict in interstate reciprocity.
But my position will always be that regardless of what I think other people should do, what level of training I think they need, I fully believe the government shouldn't be the one making the call. Individual rights demand individual responsibility and accountability. State mandated training, even if wholly beneficial, is overreaching in my opinion. If I have to choose between the risk to the public involved with leaving a potentially dangerous activity up to the individual, and freedom from government intrusion, I will choose freedom every time. I simply can't justify it intellectually that I would argue against such regulation of my 1st amendment rights, so why should I not have the same position with my 2nd amendment rights just because guns are involved? Think of it like this, how would you feel if the government said only those who were trained in sensitivity could speak publicly. Would you support that type of state mandated training to exercise your first amendment right? I doubt it. And political speech can be far more deadly than a single gun. The pen is mightier than the sword after all. So why do we stand for the government telling us what training we need to exercise our 2nd amendment rights?
