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.
You a perhaps a little too literal.
Well... as I said it could be a photo of the actual device used. They could have taken a photo of it before they planted it. I see no reason for them to tell us what devices they are using but these people are crazy to begin with.
