I think the 3rd from last paragraph covered that point, though not well enough, it would seem.
You are right to point out that filing an ASR will cause the Flight Data to be collected to establish exactly what happened, as is the case in the airline I work for.
If you have an 'event' which you know will have triggered a Class 2 report then you would be well advised to file an ASR as soon as you land.
Owning up, so to speak, will be seen by the management as the first and correct reaction to such an incident. Failing to file the report and keeping your mouth shut will not enable you to avoid the consequences. Data collection rates are over 98% so your indiscretion will almost certainly not go unnoticed.
Far better to own up, discuss why it happened and ensure that it won't happen again, if at all possible. If done properly then you may just get away with a slapped wrist and a gentle reminder not to do it again. Ignoring it will be seen as deviousness on your part and frowned upon, and quite rightly so.
There must be a 'no-blame' attitude to the use of this data until and unless it can be proved that the event was caused by flagrantly disregarding SOPs or a deliberate and reckless action. If this is subsequently proved to be the case on two or more occasions then dismissal is the only safe remedy left to the airline.
