You are sorely mistaken in this case. It did continue...and that's why this situation requires investigation.
Again, you said it wasn't started then you said the wiretapping continued. It can't continue if it never started and the FISA court does not approve warrants without evidence.
What you are trying to say here is that the FISA Court denied the warrant which means they didn't approve it. Then you assert that the court that didn't approve it were wiretapping at the time of the second request. Then you're saying that the same court that denied it for lack of evidence then approved a warrant without evidence but they didn't need the warrant because they were already wiretapping and wouldn't stop wiretapping out of inconvenience.
Your timeline and assertions make no sense.
