Once in a while a training establishment may have a staff member that over steps the mark. Time will tell.
Some operational environments are challenging, adverse and carry a degree of risk.
This risk can be managed to a degree by the quality of the training provided and the suitability of the candidates. Hats off to any individual that volunteers for these roles.
However not all measure up. Better to discover this early in the selection or training phase than later on operations where the consequences are final. Better for the individual, better for the organisation and better for the recipient of whatever service it is they provide.
