Its not only the RSAF but the various services of govt. Just look at the comments from forummers when such cases are mentioned. They are not aware of it.
As to having the coroner's inquiry - you have no idea the pressure that coroner's have been facing. During the CI when the entire lot of OCS trainers lied under oath except for one, the GCT called the coroner directly and instructed him to return a verdict and close the inquiry. As to the towing incident, SAF resisted investigation by the Police and the Coroner had to demand progress report to answers on a number of occasions.
I think I better stop here.
