This article is two days old, but seems to contain details that contradict later reports from other sources. > A FISA order is required to continue monitoring and analyzing these datasets, although the monitoring can start before an application package is submitted to the Foreign Intelligence Surveillance Court. That doesn't seem to fit with more recent claims that PRISM is just a streamlined interface for presenting FISA warrants to companies. That might be one component, but there appears to be data collection (just not analysis) pre-warrant.
