The Foreign Intelligence Surveillance Act (FISA) prohibits the U.S. government from spying on Americans without a warrant. Section 702 of the FISA Amendments Act allows the government to monitor foreign communications. Supporters argue it allows American agencies to stop foreign threats. Those against 702 point out that the FBI is able to monitor foreign conversations happening with Americans. Should Section 702 continue to be renewed despite the possibility of the section allowing collection of American’s data without a warrant?
It so much worse than this…
5 eyes (a lot more than five by now…) is basically different countries spying on each other’s citizens for each other.

So if X wants to spy on one of its own citizens, it asks country Y to do it, and then share the intelligence. No warrant needed just like when a private company gives your data over without a warrant. And unlike the loophole here, they can do it to an American talking to Americans. There doesn’t need to be a foreign national involved.
