The so-called “authorities” should explain how an uncharged device poses a terrorist threat.
It's not uncharged, it's the possibility that an item within has been modified using some sort of explosive. I think he mentioned the battery
but it was back 1 or two pages.
So, how is it a threat ? Because if the Electrical detonator is in built to the "device", then all the person needs is electricity to set it off
and this can be obtained on board.
Clear as mud ?
"Cat and mouse, but we need to publicise our knowledge so that the bad guys have to think again."
Don't telegraph to them what you are going to do. It is light telegraphing your punches.
Finally, you don't let them know what info you have as it could well give away the source,
especially for specific stuff if this is a new method, limited people would know.
