Your innocent view is quite refreshing. If only life was that simple.
In time you may well have a different opinion. Just because we live in the Uk, don't expect the authorities to be honest and fair.
From time to time events occur and authorities can behave in a disgustingly corrupt manor. Perhaps you will be fortunate enough not to experience this.
Corruption and dishonesty can occur for minor matters i.e. motoring offences to serious matters like the chap most likely fitted up for Jill Dandos murder.
The main thing is after these miscarriages of Justice occur, no one gives and damn and the authorities do their best to suppress all evidence.
Therefore in this case, it is just not worth the risk, dont fly. One way or another, if the old bill want to they'll have you. It has happened before and will happen again...nothing new.
