Data mining

Why are we worried because the government is recording our phone calls, e-mails, and for all I know, bowel movements? The various governments in the nation don't know what to do with this data.

For example, a man hired to demolish a building in Philadelphia managed to kill 6 people in the process. A cursory background check of this person would have revealed numerous arrests, two jail sentences, and the fact that he was a pothead. Why this individual was hired to handle heavy equipment when there is 7.5 percent unemployment was not explained. Clearly, the government's methods of using the information it collects on individual American citizens needs tweaking.
