Torres was coordinating the simulation, while Police Capt. Danell Adams challenged the group, asking at every juncture, "What do you do now?"
Adams was the coordinator at a recent simulation at the San Onofre Nuclear Generating Station just last week.
Such simulations are becoming more common as the Department of Homeland Security attempts to broaden training to handle potential domestic terrorist threats.
Adams said that the training is being geared to include all city employees, since any and all of them could be pressed into service during such an emergency.
