Yes, I am looking forward to hearing explanations for this as well. Looking at the Xkey score map the only significant US presence was around the NY area. But it’s more likely that there is more than one big brother here.

My first guess would be the ISP themselves rather than google. The conflagration of “pressure cooker” and “backpack” sounds like something that would come up scanning dumps from an IP but not what Google would flag.

I thought this kind of thing was also a violation of the wiretap act. Can they really just scan everything domestically for key words?
