"NJ is silent on this..."
No I'm not. I told you what offence I think he should be investigated for.
“No, of course not but that isn't what happened to Green, so you analogy is entirely spurious.”
No it’s not. The officer in my scenario discovered information that was entirely unrelated to his enquiries, did not form part of the evidence connected with the matter he was investigating and in fact it constituted no criminal offence at all. That’s exactly what happened during the raid on Mr Green’s office. The lying for which Mr Green was dismissed is also not a criminal offence nor is the possession of the pornographic material said to have been discovered. The former police officer had no business personally retaining that record, let alone revealing it.
As I said earlier, if you’re happy with police officers treating privileged information with such a cavalier attitude (because it suits their ends) you have lower expectations of them than I have.
