Well, let me say ..... a bomb don't have necessary to look as a bomb, if you know how to do your homeworks
:eg:
As example ..... take a small plastic bottle, fill it with Astrolite-G, place a reactant in a small sealed pvc foil envelope (a pair of millimeters), tie it with a thin nylon wire passing in a sealed hole of the cap ..... now you have a high-power strap-bomb that is not detected as a bomb :na:
Before you ask ..... YES, this is a valid and working bomb, we experimented it under the army ..... you only need to pull the thin nylon wire and *kaboom* ..... and, actually, real Astrolite.G, if needed, can be built with products that can be buyed freely ..... btw, sorry if i don't give detailed instructions ..... i know, there are already enough stupids that post online detailed (and 90% of the times wrong) "instructions" about how to build bombs, but, knowing that what this means, i'm not one of them
That what i mean is, anyway, all these materials are not detected as "explosive devices" (and thin nylon wire and plastic bag foil are not detected at all, on x-rays tunnels) ..... and this is just one example, there are a lot of others ..... so, if someone really want to send a bomb somewhere, there's no need of electronic circuits and metal parts .....
That one, at least at my eyes, looks possibly as:
1) the work of an absolute dilectant ..... or
2) a joke (a very stupid joke, imho) ..... or
3) the trial of someone to "fake" the shipping of a bomb, for have the occasion to spread it in the news for personal or political reasons.
..... or am i so wrong, thinking this ? .....
