It is of course important to bear in mind who is responsible.
I do hate the modern way of saying "I'm immune from blame as I am not responsible". That is similar to "we ought to do this to cover ourselves".
What we really should be saying is "lets point out this problem as that poor bloke might be caught out" or "lets do this because it is a good idea".
I'm not critiscising any of the posters here, but I love the way aviation in general has a fix it and safety attitude. Unfortunately I see too many litigious attitudes, which work counter to the good ideas which have made aviation amazingly progressive.
Gary - your last sentence sums it up very well.
