No, its not the point at all.
An aircraft used in the way suggested on here is not going to be part of any regular traffic pattern, it is not going to be involved in a number of runs to and from France filing false GARs or FPs, in short it is not going to have figured on the radar at all ever.
False GARs and FPs are used to disguise regular flights to and from the continent where the aircraft is being used for smuggling, but nothing more sinister. These records may well be used to identify traffic that conforms to such a pattern of activity.
