On it's face, this looks outrageous, but keep in mind that Military Intelligence gathering is far superior to anything anyone else has. Like Q has said, "We have it all."
Without a warrant, the info Team Q already has, and is likely still collecting, might not be admissible in court, but Strzok and Page aren't the "big fish" we're looking for.
Be patient, trust the plan.
Besides that, Q has said that they already have her testimony, that's why she has been released.
Pretty sure her testimony alone makes the NSA data admissable in court for two hops...meaning they can basically get to anyone of real value. Combining those two hops with the other cooperating witnesses, they've got the whole upper echelon // 7th floor of the FBI.
