John de Leon straddles the fence -- bravely and proudly. In the past year, the president of the American Civil Liberties Union of Greater Miami dared to write an editorial calling for Elian Gonzalez's dad to raise his own kid. At the same time he listened to complaints of excessive force filed by exile protesters who wanted Elian to stay in Miami. He filed a lawsuit against the City of Miami when its leaders tried to block the Cuban band Los Van Van from playing within city limits, and then he supported the exile hard-liners who protested outside the Miami Arena, where the concert eventually was held. He angrily denounced the ban of Cigar Aficionado's Cuba issue at Miami International Airport, yet quickly leaped to the defense of the six Cuban rafters hosed and pepper-sprayed by the Coast Guard when they tried to land in Surfside. De Leon is sensitive to the concerns of the exile community (his parents arrived from Cuba in 1959), yet he is painfully aware of its unfortunate propensity for trampling on the First Amendment. He may hold the most important job in Miami. "What we saw," he said after the Los Van Van show, "was a highly charged event on both sides. But the community was relatively unscathed by the whole thing, and I think it demonstrated to everybody that people can have strongly opposing viewpoints and be able to express them and live together in the same place." True. And in no small part because of de Leon's difficult work.
