It reads almost like criteria for a new software system presented to various agencies and before going ahead with the system they wanted to make sure they would not run into any legal problems moving forward and in exchange, a few new government positions would be created to be funded along with the new project.
Everything CISPA wants to create can sorta be done now. Private companies can spy on you. Google can collect information on you. Facebook can collect information on you. They can sell that information to the government. The government can even tell them specifically what kind of information they are looking for and those companies can focus on those specific sets of criteria.
What the government cannot do, currently (sorta), is directly spy on you via those companies.
It is one of those...
government: "hey google, if you happen to be logging everyone's e-mail and if you were to happen upon someone talking about not paying their taxes...we would be willing to pay for that. but we're not telling you to go search for that information...*wink* *wink*"
