Jonti said:Just suppose, just imagine (it seems to be the case) that the Met was given the alarming information by Government sources.
Off-the-record briefing and counter-briefing continues apace:
the Met said:Why were police at the house?
Senior officers have said they received "credible" intelligence suggesting a chemical-based explosive device was at the house.
Who produced the intelligence?
Primarily, MI5, the security service, which has a prime role in countering terrorism and works closely with Scotland Yard. It is understood to have come from a human source.

MI5 said:it emerged that the man who had passed the specific information that led to the raid in which a man was shot last Friday was a police informant who had been providing intelligence about the activities of alleged Islamist militants for several weeks.
This was despite previous reports quoting police sources that suggested the informant was being handled by the security service, MI5. It was the police who passed the information from the informant to MI5 officers to assess it, the Guardian understands.

"It was themmuns!"
Government involvement would be quite extraordinary. Especially since a major concern for both the Met and MI5 is campaigning at the government for more funds.
The simplest explanation, however, remains: "source said something really scary, followed by major fuckup".

MI5 said:a rift deepened between police and MI5 over how intelligence reports were handled. Security service sources are openly questioning police tactics and claiming they were far more involved in intelligence-gathering than they have admitted.
