Really?
It could be a prototype. They could have taken it before the flight? It could be a lie.
The answers to your question are self evident.
I understand what you are saying and already thought of those answers.
My question still stands as the TEXT ON THE PHOTO says it is THE device, not THE TYPE OF DEVICE.
It also may simply be due to 'translation'.
A point made on another thread is... Why would they show it to us so we could be more prepared to prevent such bombings ? Could it be they 'gave' us that picture to throw us off to what the real bomb might look like ?
I am skeptical of everything because most of the pablum we are fed is made from cow manure.
