His "sheer weight of expertise" is still light on what else might cause the metallurgical evidence he discovered. We discussed this at some length, whereupon you too admitted you were not an expert in metallurgy and could not evaluate the claims independently.
You claim he is an expert in explosives and that upon the strength of that expertise he identified an object in a photograph -- which mysteriously later disappeared -- as a bomb. Experts in bombs can identify bombs because they know what bombs look like. They know what bombs look like because they've seen a lot of prior bombs. What demonstrates expertise is not so much, "I think this is a bomb," as it is, "This is a bomb because it looks like this other thing that I know from experience to be a bomb -- here let me show you." Funny how Braidwood can't seem to make that claim.
No, your invocation of Braidwood is subject to ridicule, for the reasons given.
No, your critics are not wallowing in the throes of melodramatic terror at the prospect that you might be right. They're wallowing in amusement at your antics when you're shown to be wrong.
