A U.S. district court judge this week dismissed the $5 billion lawsuit against New York City and Motorola filed by the families of 12 firefighters killed when the World Trade Center collapsed in the aftermath of the Sept. 11, 2001 terrorist attack, the Wall Street Journal reported. The suit had alleged the firefighters died because the radios they had been issued didn’t work properly in the high-rise complex, and that both the city and Motorola knew of the problem and failed to take appropriate actions. Judge Alvin Hellerstein ruled that because the families had filed claims with the Victim Compensation Fund, they were ineligible to claim damages in a civil suit.
