Ms Isolde Goggin:

There is precedent. There is also precedent for whistleblowers, who can also provide useful evidence. A person does not have to have been guilty to come forward with evidence. What we are looking for are nuts and bolts. We are looking for names, dates and the places things happened. If our professional criminal investigators are satisfied that they can ground a warrant on it, they can apply to a District Court judge for a warrant to search a specified location for information between specified dates relating to specified people. Without it, it is a fishing expedition. It is a trawl.
