The Wall Street Journal's Rebecca Smith reports that a former Federal Energy Regulatory Commission chairman is acknowledging for the first time that a group of snipers shot up a Silicon Valley substation for 19 minutes last year, knocking out 17 transformers before slipping away into the night.
The attack was "the most significant incident of domestic terrorism involving the grid that has ever occurred" in the U.S., Jon Wellinghoff, who was chairman of the Federal Energy Regulatory Commission at the time, told Smith.
