I have to agree with jaba-who about trolling back through history to find fault. I worked for a very large state organisation and if there was any complaint of any kind, both internal or external, your complete history, with notes and reports submitted and collected over many years were examined to verify any allegation of wrong doing.
I have been both investigated and also conducted investigations on others so I know how this works. I doubt that CASA would be any different to any other government organisation . Even electronic footprints are looked at, both business and private, just like IN THIS FORUM, where some of you may have left your antecedents electronically for anyone to read.
food for thought?
