According to the report, Deputy Solicitor General Paul D. Clement told the court that U.S. law enforcement would be crippled by a federal appeals court's rulings in favor of a Mexican doctor who alleges he was kidnapped in Mexico by the U.S. government and one of its Mexican agents.Dem Convention Forces Closure of Major HighwayThe Boston Globe reports that the Secret Service insists that for security reasons Interstate 93 and a major commuter rail station must be closed during all four nights of the Democratic Convention in Boston.
