To be fair, there are many (if perhaps not a majority) of people with guns who are horrified at what the NSA is doing. And in all likelihood, their owning guns probably doesn't dissuade the NSA from spying on them further.

It could be that PRISM was a related router tapping technology or something else entirely.
