Here's something interesting I came across by accident: an interview with former Barcelona mayor Pasqual Maragall in the International Herald Tribune from 1991, the year before the Olympics. Note the concern with street crime and heroin addiction; one has multiplied and the other has disappeared, because all the heroin addicts got AIDS and died. Maragall is rather dismissive of Catalan nationalism, hopeful about the European Union, and concerned by ETA terrorism--some things never change. Problems like immigration had not reared their heads yet.
One thing that all of us who criticize Maragall have to admit is that the Olympics really were a great success, and he probably did more than anyone else to make them one. Too bad he was such a lousy regional premier.
