All that physical training helped Garcia have the stamina to stay in the fight and save other officers. It also made his reaction time quicker.
"When I shot that dog, I saw the sights come up and a round went off," he says. "It wasn't like it is on the range where you feel like the trigger press is taking forever. It went off like I had a one-pound trigger pull on it. Once the sights came on target, the round went off, it was a good hit, and the dog went down."
Garcia also thought like a SWAT officer during the incident, cataloging pieces of information that he could use later to his tactical advantage against the gunman and to aid other officers.
"They say that one of the first feelings you lose is your sense of touch, or taste, and other things become excluded," he explains. "But I could see everything. I didn't get any tunnel vision. I heard the bangs, but they weren't incapacitating in any manner.
"Once I got to the command post, I had a picture of the house in my mind. They were trying to get a layout of the house, but didn't know I had actually stepped into it. I was able to clarify things, and tell them what was wrong with the layout they'd drawn up. 'No that's wrong because the dining room is on the left, the kitchen is straight ahead, the living room is on the right,' I told them. I could see all that. The stairs came up, the stairs came back this way. So my tunnel vision wasn't like looking through a straw.
