I am sorry but I am afraid that you are mistaken on some of the issues and other son here will advise better.
The requirement to register comes in later this year, but it will not be your local police but a central registration system though yet to be announced. You will have to register with the new system, regardless of what you have passed to the police.
Police powers are still to be agreed. The results on a recent consultation have just been announced. Have a look at this link to get a clearer understanding.
Enjoy your flying, and there will always be someone here to guide you if you have any questions.
