meeting this morning. kris sanchez joins us live from south san jose with what regulators are saying about the concerns of a possible terrorism element at this substation. >> reporter: well, let's start by saying the metcalf substation here in south san jose is better protected than last april when someone took a rifle and shot out 10 of the 12 transformers, the cpuc and public will hear what the utility knows about the incident that took out power as well as cell and landline service including 911 system for the county. back in april of last year, theories went from vandalism to terrorism against a vulnerable infrastructure. the fbi did not classify the attack as terrorism but in february of this year a former federal energy chief told the "wall street journal" he considered it the most significant indent of terrorism involving the power grid. we did meet one of the security guards already this morning.
