i'm trying to survive somehow. >> all of the terrorists are killed and 130 of the 850 hostages die as a result of the gas or lack of medical attention. a memorial stands outside the still functioning theater as a stark reminder of that dark moment in recent russian history. >> coming up, a police taser cam captures a point-blank shootout pitting cop against hostage-taking gunmen. >> i thought he was going to shoot me. i was looking straight down the barrel of the gun. >> when "caught on camera: hostage" continues. ed people a simple question: can you keep your lifestyle in retirement? i don't want to think about the alternative. i don't even know how to answer that. i mean, no one knows how long their money is going to last. i try not to worry, but you worry. what happens when your paychecks stop? because everyone has retirement questions.
