If the NSA were law enforcement, that might be a reasonable conclusion. NSA shares a lot more than many people think they should[1], but it isn't like German or Australian local police, or (usually), even local US cops have access. To have reason to seriously consider them in your threat model[2], need to do something that encroaches on the interests of particular power centers. Aside from what most people think of as actual national security-type things, drugs are a good way, as is, apparently, majorly pissing off the copyright cartel.

All that said, I do suspect that we will hear more about surveillance from the various spook agencies (not just the NSA) being laundered to more mundane criminal cases over time. We know this happens with the DEA and FBI; we know the DEA feeds local law enforcement carefully laundered intelligence; I'm really curious about DHS, ICE and major-metro police agencies like the NYPD's relationships, possibly through what amount to cutouts.
