You should never, ever, take legal advice from a serving police officer, AuntPolly.
I've provided the Sentencing Council's guidance and they clearly state that accepting a CR involves accepting responsibility. It goes on to say that, in certain circumstances, that acceptance can aggravate later offences. It would not be able to do so if the CR did not involve the equivalent to an admission of guilt.
However, in case you're not convinced by that (after all, what does the Sentencing Council know about such things?) here's something less formal:
https://hub.unlock.org.uk/knowledgebase/community-resolution-order/
"Does it [a CR] involve guilt?
Yes – you have to make a clear and reliable admission."
Or perhaps this:
https://informeddissent.info/cautions-and-community-resolution-orders
"Community Resolution Orders Summary
It’s like an apology for what you have done. You have to make a clear admission of guilt."
If, when explaining the process to you, your local Bobbie suggested it was not an admission of guilt he was misleading you because it most certainly is. It doesn't matter how clear cut or otherwise the matter is. The person accepting the CR admits guilt.
Police officers have a vested interest in persuading people to accept CRs if they deem it is appropriate. It satisfies (or should satisfy) the victim and it saves him a lot of time compared to prosecuting the offence through the courts. Officers may therefore, in order to get the recipients to accept the offer, whether by accident or design, provide information that is either misleading or simply incorrect. That's why (among many other reasons) you should never take legal advice from a serving police officer.
