Hb1hf Oh no. The FBI just admitted on a congressional hearing to doing almost a million searches without no warrant whatsoever.
That's metadata, which can be telling and only requires an administrative subpoena signed by the FBI themselves - and the NSA has been doing this for well over a decade and it has not caught a single terrorist as was the plan. I was referring to E911 or cell tower location real-time tracking which requires a warrant from a judge based on probable cause. cell providers and ISPs will not do real-time without a warrant form a judge.
Hb1hf They don't need to. 5-eyes agencies spy on other 5-eyes countries' serfscitizens and share the findings with each other.
They spy on each other and share the data? No, the intelligence agencies in the 5-Eyes don't admit they spy on other foreign agents. The U.S. does collect mass foreign communications metadata and shares it with the intelligence agencies of those countries. Not aware of many crimes being solved.
Hb1hf Very likely they have no issue presenting illegal spying in FISA courts.
As I mentioned, no doubt corrupt FBI agents have used parallel contraction (thus fake evidence) before FISA courts. The FBI used the bogus Steele dossier (and knowing it was bogus) to get a FISA warrant to tap the phone of Trump campaign worker Carter Page in 2016. This has been proven. Note to spy on the U.S. citizen and listen to conversations, they got a warrant from a judge - albeit by giving fake evidence to a judge they knew was fake. Point being the FBI is not just hoovering up real-time location data and wiretap data without a warrant from a judge. The FBI is hoovering up metadata on who you have called. They are buying metadata on past locations from like apps with location data from your stock Android phone. However, and as I pointed out, for real-time location tracking (or real-time wiretapping of phone conversations) cell providers/ISPs/big tech/little tech won't give this up without a warrant form a judge. Could a warrant request be based on bogus info that tricks a judge? Sure, but under federal law a judge can only issue a wiretap warrant for 60 days (location for 45 days) and to be renewed the FBI needs new bogus evidence to trick a judge once again, which is not as easy.
