I'd like to address people that question Q if he knew why didn't he do something? A lot of intel is picked up through phone conversation's. I know this because I worked with it and know how it work's. He may have received the intel that something was about to happen. But unless the target says where and what time it could be anywhere. I'll say this. We used it south America for drug busts. We could listen into the conversations. Pick up where and when a load was coming out of the country.
