in the mail about the acid attack police say officers engaged with the informant to identify any VIABLE LINES OF ENQUIRY NO REASONABLE LINES OF ENQUIRY HAVE BEEN IDENTIFIED AT THIS TIME so what they mean is she called them to report it but there is no evidence at all to support that anyone actually did it(i suppose they could not come out and say directly we have had dealings with the informant before and can not believe a word she says)and notice she says the security at the mucky mansion is being taken seriously by everyone(she does not actually say by the police)she means the bank who now own the house
