I'd like to jump on the back of this and make the point that, referring to the clock project in question, it seems a lie to label the item as a "hoax bomb" as if it were actually intended to even be a bomb, let alone an article of the hoax variety. Not to mention the obvious claim of guilt by association that the prosecuting argument seems to imply, I would add that it also useful to distinguish the reality of the situation so as to ensure that "hoax bomb" doesn't catch on. "Clock thought to be a bomb" would be a more accurate representation of the situation.
