RS- I would be interested to know whether the investigations you were involved with were conducted in Australia after 2003. In an Australian investigation your legal representative is there for moral support and cannot direct you to not answer a question. As I said ,if an investigator in Australia, makes public information provided then he/she goes to gaol. Not a consequence to be taken lightly. As far as I am aware the ATSB only has one lawyer on staff and he/she does not direct an investigation.
The statements and evidence gathered by the investigator are not available to any other agency. Probably drifted this thread far enough
