That's what they said before the Snowden leaks. The Snowden leaks and latter revelations showed they were lying.
For example, they use a different meaning for the Word "collect." Instead of interception and storage of data, collect means an analyst looked at it. So, they technically weren't collecting U.S. citizens' data if analysts hadn't looked at that specific data yet. Technically... based on a strange definition of collect.
They originally also said this was limited to terrorism. Later, data showed they were looking at many more crimes. They were also passing the data onto many agencies. They were told to use "parallel construction" to deceive people about how they got that data.
Finally, BULLRUN and ECI-classified level showed they were weakening U.S. security standards, but pretending to strengthen them, so they could attack U.S. systems in secret at any time. Per "Core Secrets," they were also having U.S. companies give them backdoor the FBI could "compel" them to make (somehow).
With all that, they were caught lying under oath repeatedly. They got criminal immunity for that, too. I don't believe one word they say at this point. I also assume they're doing the same things they repeatedly lied about before and for which they can't be prosecuted.
