3. 5 parts? No thanks

If there's a part that answers my question -- why should we believe the NSA had access to call source numbers? -- please point me to it or give me a summary. I know enough about how telephone switching works to know that the receiving switchboard does not receive metadata -- it does not need to know the calling numbers as Bamford claims -- and that the only way the NSA could get that data is from one of the telco switches involved in routing the call. If he can't supply the technical details of how that was done, then it just smells like bullshit.
