> Discussing/brainstorming this in a public forum is volunteering your brainpower in support of murderers.
If you think that you in a few moments on the back of a napkin will come up with something that someone funded and fuelled by an ideology that they are willing to die for can't with months of planning, then that's arrogance of an epic scale. This is as ridiculous as don't talk about hacking/spoofing/phishing because otherwise the bad guys won't figure it out.
A worldwide forum discussion among dozens of creative people out to one-up one another on clever strategies for killing another human may well put an effective idea in front of someone who might put it into practice.
There are occasions for discussing mechanisms by which one might construct such a weapon. I feel that this moment isn't one of them. Just because we can talk about it (and must be willing to defend the right to talk about it) doesn't mean that we should do so in this context.

To discuss specific implementations of an attack would seem to violate both a personal code and what I imagine to be the spirit of HN.
