>In the 2018 case Carpenter v. United States, the Supreme Court affirmed that individuals have a reasonable expectation of privacy in their long term movements (even in public spaces) and, because of that expectation, queries into long term location tracking data constitute a Fourth Amendment search that requires a warrant.
I suppose they would also have to argue that they are not the actual target of the warrant.
And if that did happen, I feel like one could have a strong case against it by claiming that there is no reasonable way to have had that information without obtaining it illegally.

And that may be true, however Carpenter v. US established that long-term tracking of a person's location without a warrant is still not allowed under the Fourth Amendment.
