Why should terminology be changed to appease a bunch of people on the internet who insist that the first use they heard of a term must the only correct one?
Nobody is confused here - the difference in definition based on context is blindingly obvious and, in case anyone had failed to grasp it, the specific and precise legal definition is being quoted as well.
The fundamental thing is that no, the legal definition is NOT, in general, being quoted. Sure, in this discussion, it was. But in medias the world over, including in the US, it's not. All that's being said is "Charged with using a weapon of mass destruction". Which, yes, to the vast majority of people, is going to be equated with the completely false charges the US government made against Saddam to justify invading his country. Not just because it's the first way they heard it, but because it'S the only way they ever heard it used,. and, you know, the one that's entirely dominated mass media for the past decade and some. It's perfectly reasonable for people to link the two, especially when the other definition is much more sensible than this one.
What this comes off as is not "oh, well, must be different definition". It's "Wow. Americans are such drama queens aren't they? Always blowing things out of proportion when anyone goes after them." I appreciate that it's not the case, but it's what it looks like.
Even knowing the legal definition, I'm not likely to change my mind on that. Change who I blame, yes. It's obvious now that the DOJ is not to blame, and instead what's to blame is the toad-like brains that Americans keep filling congress with, and their complete lack of anything remotely approaching basic reading comprehension and writing abilities. Because, as previously mentioned, even the Canadian criminal code is better written than that, and the Canadian criminal code is an utter disaster and a half.

VRWC : I used to be enough of a military toys geek as a kid/teen to know about the NBC term. Of course to most people, NBC stands for, well, NBC, but that's besides the point here.
Also I'm not sure that I would restrict this to nuclear, bacteriologic, chemical when it comes to weapons of mass destruction. I could imagine SOME conventional bombs (eg, the infamous MOAB) being legitimate contender for mass destruction. Heck, I could even entertain an argument that the planes of 9-11 were used as weapons of mass destruction.
But when it comes to explosive devices that are far under the basic destructive potential of commonplace, everyday-use (while at war) military weapons...that's just too much stretching "mass" destruction. Which implies something especially destructive, not "anything with even the remotest bit of destructive potential".
