John Kerry's stated purpose for being in Philadelphia Thursday was to speak to delegates at the NAACP's annual convention. But the presumptive Democratic presidential nominee also managed to leave town with more than $500,000 in his pocket, largely courtesy of the city's trial lawyers, large firm lawyers and their clients.... Though event organizers played down the role of trial lawyers, they did say that more than half of the funds raised for the event -- an hour-long meet-and-greet session for contributors held at Philadelphia International Airport Thursday afternoon -- came from trial lawyers.
