Colonel Diaz has said that Noriega planned the assassination of former President Torrijos. that he ordered the brutal murder of opposition leader Hugo Spadafora. that he rigged the Presidential election of 1984. and that he has taken millions of dollars in bribes in exchange for Panamanian visas and other favors.

In contrast. the response of the Panamanian people has been heartening.
