I read in Margaret Trudeau's book that she hated those black books that Mr. Trudeau brought home at night. As you'll understand, he must not have been the only Prime Minister who worked at home, and, as you can well imagine, a number of ministers work at home as well. Consequently, they don't always have their eyes on the documents. A mole can indeed open documents and see them.
In that sense, are you prepared, in the case of an unusual relationship, to enter that person's name in your data bases to see whether there are any reliable indications on the relationships that he or she has had with organized crime?
