Also yesterday: the police refused an OIA request for information on
the use of coercion, psychological persuasion and/or manipulation by undercover officers to entice someone to commit a criminal offence.
as telling us whether the police solicit crime would "prejudice the maintenance of the law, including the prevention, investigation, and detection of offences".
Given the explosive nature of the allegation, and the impact of such activity on public confidence in the police, if they weren't doing it, they would deny it. Therefore, the conclusion we should draw from this is that the police are coercing and manipulating people into committing crimes, which they can then arrest them for.
(This of course assumes that the police are sensible and concerned about our trust in them, rather than reflexively secretive authoritarians who believe we have no right to know or question them. But there are consequences to such fuckwittery, and the destruction of public trust is one of them. If they are in fact not doing this, then all they have to do is issue a statement...)
