Prosecutors insisted that Ivan F. Boesky got a fair punishment for his crimes, despite the convicted speculator’s plea for more leniency from a judge who sentenced him to three years imprisonment. Boesky asked U.S. District Judge Morris Lasker late last week to reduce his sentence for conspiracy to violate securities law because he has provided prosecutors with additional evidence on “new topics, new transactions, new relationships and new securities.” In a two-page affidavit responding to Boesky’s request, Assistant U.S. Attorney John K. Carroll said Boesky is continuing to cooperate and “the government’s investigations relating to information he has provided continues.” But Carrol also maintained that “in the government’s view, Boesky’s three-year sentence was and remains an appropriate sentence in light of all the competing factors.”
