Fiona,
I heard your piece on Radio 4 the other day and at the time, I formed two opinions:
1. You were guilty as charged and managed to get away with a con by running away and protesting from a distance.
or...
2. This was a horrifying example of a "stalking" police officer who, for whatever reason, had a vendetta against you.
Quite honestly, I don't know what to think. However, your comments here lead me to believe you know a lot more about this man than we do.
PPrune gets it wrong from time to time but when it comes to righting wrongs or outing charlatans, it's quite successful.
Perhaps your involvement, if not breaching any libel laws, could tick both boxes?
