On Amendment #17:
I realize the lack of credibility the following will carry, but here goes.
This whole issue started back in the Spring of 2011 when Ron Glidden authored an article in MCOPA's magazine arguing that the "for law enforcement purposes" language in MGL 140/131M prevents officers from using AWB restricted items, including large capacity magazines, except when on duty; further, in his view, practicing (which many officers could stand to do more of) was not an LE purpose. While I have some disagreement with that legal interpretation given how the ATF previously interpreted it under the federal ban, I think his advice was meant as a warning to chiefs to follow the law strictly to be safe. Additionally, prior to the article, chiefs had been providing letters to some officers to purchase for private AWB items, similar to non-AG Approved Handguns. Glidden also took this practice on as unlawful, and in the end, I think he was legally correct on that view, given the law exempts possession only--not buying, selling, or owning an AWB.
What followed was a bit of shitstorm, as within a few months, EOPSS sent every MA dealer a warning to abide by what was essentially an reincorporation of Glidden's opinion as it's own. The problem became that no one knew what to make of all that, and it descended into all sorts of legal conjecture by liability-weary chiefs, with some departments advising officers they couldn't take home duty weapon magazines or carry their issued weapons off-duty. (I also think this statute is overridden by MGL 41/98, but that's my view.)
The purpose of Amendment 17 is to add some clarity to this foolishness, not to give LEO's free reign to strap on whatever they want to a personally-owned AR. Frankly, I think they did this for a lack of time and imagination, and it's seen as a quick fix by legislators to avoid more specific but complicated language given the short timeline they're under. With that said, the law still wouldn't permit private ownership--merely possession.
I think that's the distinction that would be made in any case challenging the AWB on an Animal Farm argument: all gun owners vs. on-duty law enforcement--provided it even gets that far. I don't see what legal theory one could raise to even argue that point. Which is why #17 will do noting to help repeal the AWB.
Not really. That's not quite how the equal protection clause works. Non-LE gun owners are not a suspect class. At least, not legally.
