The royal “us” in “keep us safe”:

Huffington Post has unearthedNSA documents, provided by Edward Snowden, which describe how “personal vulnerabilities” could be learned through electronic surveillance, then exploited to undermine a target’s credibility. Among the vulnerabilities mentioned are “viewing sexually explicit material online” and “using sexually explicit persuasive language when communicating with inexperienced young girls.

The document actually discussed six specific targets, and it should be pointed out that none are explicitly referred to as being involved in terror plots. All things considered, though, it seems like a very tangential way of preventing a terrorist attack on the US.

The “us” is clandestine government interests.
