You're calling her a liar based on her second hand account of what JTTF (not FBI) agents told her husband. But the Google searches might have been only one element of what led the agents to go knocking on her door. We know for a fact that the feds do get people's Google searches after they've convinced some rubber stamp court that someone is suspicious.
I have no trouble believing that the FBI would do things that would compromise the fact that they collect information about searches for targets of investigations. That's a very different compromise than the one that reveals they dragnet all Google searches for lead generation.
