Russian Spies in American Suburbs: Shades of the Cold War?

Ten Russians posing as ordinary Americans, including parents with children, have been arrested as "deep cover" spies after seven years of investigation by the FBI. Their alleged paymaster was picked up in Cyprus. US officials reportedly were astonished when Christopher Metsos was released on bail in the first place. Both countries say the incident won't damage relations, but a lot of questions remain. What were the agents doing here decades after the Cold War? Why have they been arrested now? If they posed a danger to national security, why don't they face more serious charges? Does the US have its own spy rings in Russia? We hear from a former CIA agent, a Russian scholar and others.
