That seems to be the gist of it. I would give most weight to #4, as # 1-3 rely on ideological arguments. #4, however, is indisputable fact.
Good. I'll add Gaiudo's point #5, and address them one by one:
1. I don't think I'm wrong about the 2nd Amendment, but if such a proposal is enacted on a federal basis, I'm sure we'll find out one way or another, as it will no doubt be challenged.
2. I disagree about the police chiefs being trustworthy. There are reasons they have risen to the level they have, and not all of them are political. I think it's rather cynical to accuse them of dishonesty or ulterior motives. In any case, I find their arguments on this issue to be compelling.
3. I reject all slippery slope arguments. If someone presents me with what I consider to be a reasonable proposal, I will be in favor of it. If I am presented with an unreasonable proposal (such as seizure of guns from private homes) I will be opposed to it.
4. Let's take this in parts:
(a) Nothing I can do about the millions of high capacity magazines already in existence. However, a study I read in the Washington Post reported that the previous AWB ban between 1994-2004 did have a significant effect on the availability of these magazines. My main rationale for believing that, with such a ban in place, these crazies will not use them nearly as often is that they are just that: crazies. They are much more like to obtain whatever is easily obtainable. Make these magazines illegal and they WILL use smaller magazines.
(b) While many of you are gun experts and can reload in 2 seconds or less, I don't believe that many of these crazies can. Again, I have to rely on the law enforcement experts that you guys find disreputable, but they tell me that these crazy people struggle when trying to reload and thus can be taken down at that time. Therefore a limitation saves lives. Someone actually posted if it made any difference if 10 people die instead of 17? My answer is absolutely yes. That is the point, the ONLY point of this ban.
(c) The examples of Columbine and Virginia Tech demonstrate that this proposal will not be 100% effective or even 70% effective. In fact, there will be no way whatsoever to prove that it was effective at all if it's put into place, and no way to disprove your arguments that it won't make any difference. I believe it will, but I can't prove a negative. Still, I think that overall lives will be saved.
5. The issue of whether or not one's home defense is significantly hurt by not having these magazines is debatable. I don't think it is. I believe that most of you that own high caliber magazines do so not for defensive purposes, but because you enjoy owning them- in short, for personal pleasure. Absolutely nothing wrong with that, except in this instance I think it has to be limited in order to protect society against crazy people.
