He only describes his view from inside the system NSA. But it is the outside which really worries me. Governments and legal boundaries can change. DHS and TSA were such changes. And both agencies have a big impact on the lifes of citizens and visitors. OP admitted, that NSA already gathers data of US citizens. But the current legal boundary prevents analysts to just add a "selector", except when it is allowed by a (secret) court. So the data is already there with the technology to query or filter it, which is a bad thing in itself. But it is a tiny change in the law, that would make it legally right to include US citizens' data into the query. Looking back at DHS, TSA and the overall militarization of the security forces, it is not hard to imagine that NSA is an easy pick for a reactive government responding to the next terrorist threat. BTW. When have government institutions ever been dissolved? Isn't that a lot harder than creating new ones or changing the rules in favor of more control?
