It is an issue of fact.
And, missing both a detonator to initiate the explosion or, from all that I can tell, the lack of an actual explosive "main charge" [rumors are that it was sulfur powder- which is not an explosive], and further having a clock that has no alarm function to switch power to detonate the detonator, and further having no stored electrical energy (battery or capacitive discharge system) to be switched by the non-existent, the facts appear to be that this was utterly and totally a hoax, e.g. a fake bomb.
Calling it a real bomb is like calling a pistol shaped piece of wood with a hole bored out in the fake muzzle and filled with ground black-pepper a real handgun. It's still fake even if I pack the fake black powder with bird-shot.
I keep hearing the TV guys saying they contained black powder. If this idiot handled this much black power he is lucky he didn’t blow himself up. Black powder is quite volatile. Just a spark from static electricity and it ignites all at once.
