So lets look at the alternative. Whatever airline you work for keeps safety information "secret" and a preventable accident happens. What will the press do then? Concievably it could be the end of the airline if the press hound it for too long. "XXX Airline has accident they could have prevented" is hardly good press either.
Its like the modern approach to allergies. In order to prevent the lawyers taking food companies to court, now almost everything says "may contain nuts". That is more of a hinderance to allergy sufferers than before, as now previously safe foods are marked as unsafe and unsafe foods have the same markings. It would be much better to have "contains nuts" and "does not contain nuts" and nothing in between, however the lawyers got there first.
The safety issue is the same thing in a different guise. The lawyers are the press and the allergy sufferers are the pilots in your airline. I for one am very happy to read safety related stuff in my airlines magazine. While the press are a worry, they shouldn't control us, as they are unelected, unaccountable and generally dim. Ddo we really want our descisions made by these people? If the workd was run like that we would have such little progress that we'd never have aeroplanes in the first place. Just remember what the papers said about the first aviators. They ripped them apart for doing "impossible" and "stupid" things. If they hadn't perservered, the world would not be such an interesting place.
Stand up to your top brass, they are the ones making the error, not you, even though there is some truth in their argument.
If you think the cost of safety is high, count the costs of an accident.
