Does "sentence" means "a court "judgment" here? Or it just means "a grammatical unit"?
Context:
The reference to "patterns of suspicious activity" is particularly notable, because it is tied directly to an F.B.I. investigation of "recent surveillance of federal buildings in New York." A portion of that sentence was revealed during testimony
Thursday by Condoleezza Rice, the national security adviser, before the panel investigating the Sept. 11 attacks.
