Yes, that happens all of the time but one difference here with Tucker is he was deliberately "unmasked." Normally when an American is caught up in foreign surveillance, their identity is blocked out or masked, "incidental collection" as you said. Someone purposefully unmasked it. And someone purposefully leaked it. The same thing was done to General Flynn.
