That ok if you've got the money to do it.
No money required!
Personally, I like to sort my own problems out.
Even if that means breaking the law to do so?
Apologies, misunderstood your post.
I had a problem with someone harrassing me. To the point of hundreds of pounds worth of damage, car tyres slashed, death threats ( i recorded these on my phone recorder). Several officers told me not to worry and they would have 'word' with him, none of them did.
Eventually found an officer that could be bothered to do something and it went to magistrates court.
CPS decided it wasn't likely to end in a procecution as there was a lack of evidence!!! I had voice recordings of him making death threats FFS!

Anyway, post that, he was still causing bother. My only option was to take out some sort of restraining order (via private solicitor) on the guy which would if I remember rightly cost several hundred pounds.
Absolute waste of time.
As far as breaking the 'law' goes, I wouldn't even have to think about it. The 'Law' is responsible for some absolulely attrocious things in this country, more often than not, supporting the offender.
I have a very strong moral compass, I live by that. It's quite clear to me the difference between right and wrong. I've broken a 30mph limit, I've swore in public, I've even driven without my seatbelt on!! The 'Law' would make me a criminal whilst it lets rapists paedophiles and murderers walk free. I simply can't live by something as ridiculous as that.
