Is nothing secret?

Waking up this morning to a brand new day, refreshed and feeling brand spanking new with none of the spanking if you know what I mean. Anyway first thing I hear is that policemen don't trust anyone and by anyone I mean the attorney general why else would you tape conversations. Oh yes for your memoirs. Was sir Ian Blair wrong to record the conversation? Only if he believed by doing so a crime would be uncovered and prevented. As there was none then he was wrong it's as simple as that. My question is how did they find out? somebody must have been recording something or somebody knew something.
