Yes, "collection," key word, that's obvious from what I wrote. Your link also specifically uses the phrase: "without obtaining separate court approval for each search." That's because they receive a blanket warrant giving them authority to look at all relevant information. So when the FBI is looking at Osama's phone call list, they don't need to get a specific warrant for each individual Osama is talking to to get their records.
If you have within your circle of friends someone the FBI is investigating for terrorism, I think you have bigger problems than the FBI having your call logs.
They don’t need to be collecting Americans phone records. Only a fool thinks that’s freedom.
