Yes, but Felix, the person who has reported a non crime committed by a person whose completely reasonable and legal views they happen to disagree with is the person who should not get their way.
Because they have done something wrong, and the other person has not.
Because they mistakenly believe the police are actually the Stasi, there to enforce their belief system on unwilling dissenters, rather than public servants who are paid to keep us all safe.
Because they are wasting public resources reporting these non crimes to the police and expecting you to do something about it, thus hindering your ability to do your actual job, which, in case you need reminding, is to keep us all safe.
Being impartial does not mean you need to go and intimidate people who have done absolutely nothing wrong just so the twat who reported them to you for a non crime feels that something has been done.
The only thing that needs to be done in this situation is that the twat who reported them needs to be put firmly back in their box.
Seriously. Impartiality! I've heard it all now.
If you think Impartiality means you need to pander to the feelings of someone who makes vexatious complaints to the police then you SERIOUSLY need to go on a refresher course about your duties towards the public.
Even I know that's not what your duty of impartiality means, and I'm not claiming to be a bloody copper!
Good grief.
