WHEN showbiz lawyer Michael Brereton travels these days he packs his suitcase thoughtfully in order to help customs officers search him at the airport. "Everything is laundered and folded so they can take it out and I can put it straight back in," says the man who was fingered by the Australian Crime Commission as Mr X. "It first happened in June 2002," Brereton says, "And I've been searched every time except two, probably 20 to 30 times in the past four years." Given the inevitability of being picked over at customs, Brereton presumes the searches are more about intimidation than revelation. There has been a lot of intimidation going on over the past year: accountants and lawyers dragged out of bed, their houses and offices searched, interrogations on the front lawn, warnings that if they tell their clients the Crime Commission is now pouring over their files they face five years in jail.
