Former FBI director says United States intelligence officials must do a better job analyzing the mountains of global Internet, telephone and financial data they collect to thwart the cyber terrorists of tomorrow.

Speaking to The Associated Press ahead of a global intelligence forum starting Monday in Ireland, Louis Freeh says hackers seeking to take control of, or take down, key pieces of U.S. infrastructure could do more damage than the 9/11 attackers .

Freeh says computer systems controlling power plants, the navigation of aircraft and ships, and even the switching of street lights could be hijacked to gridlock societies and inflict "mass destruction on life and property." Just because it hasn't happened yet, he says, doesn't mean other governments' cyber-spying agencies cannot do it.
