The Northern Territory Government and various bodies closely associated with the government (so-called independent boards, bodies, societies etc.) have a long history of retaliation against those who have digressed from the NTG narrative.
According to this narrative Rolfe should have been found guilty and now should be inside a prison. When things do not go to plan for the NTG it becomes vendetta time. Anything and everything will be used against the subject of the vendetta. No amount of money will be spared in pursuit of an individual.
Police, nurses, medical doctors, teachers, lawyers and various other public servants who have refused to be involved in cover-ups, have questioned mismanagement or have gained a victory like Rolfe have all become subject to the NTG vendetta.
There are those in the higher echelons of NTG agencies who become fixated with scoring a victory over an individual at any cost. The Trust has been provided with reliable information from several sources to verify that NTG officers will tell lies and commit fraud to carry out a vendetta. It is win at all costs for the NTG.
So it seems Zachary Rolfe is not the only NTG employee with a target on his or her back.

Remember that the Northern Territory Government has vast amounts of taxpayer dollars to pursue an individual. So solicitors, barristers and investigators can easily be engaged by government, cost no object.
