Is it unreasonable to ask a grown up what his opinion is based on?

If you search "terror threat" with either "Mail" "Guardian" or "BBC" in front, you find the very same stories.

Why will you not tell us why you think there is " a politically-motivated ruse, designed to take people's eyes off other issues which are equally serious and, from a social and economic standpoint, just as dangerous?"

It is an extraordinary theory.
What is behind it?
Anything?
Nothing?
