Tony Campolo -- and the guy is so low-key it's hard to find anything on him other than the several Google pages' worth of self-promotion -- has an organization (EAPE) which has worked in The Dominican Republic and in Haiti. Haiti is pretty much a hell-hole and DR is supposed to be almost as bad, although they do produce incredibly good baseball players.
Perhaps the issue is to compare the Dominican Rep before and after Tony's group impacted it.
Oh, I know. Such a sensible Christian approach to assessing Tony and group's efforts wouldn't be near as much . . . devilish fun?
