Really now, why do people stubbornly adhere to the belief that Government entities require warrants to determine anything about you - like, where you are at this particular moment or the GPS coordinates of your location last Tuesday at 17:42hrs UTC? ... And pretty much anything else you can dream up about yourself: The content of conversations with others, everything you've purchased at anytime, what you are likely to eat for dinner this coming Friday, your medical records; you name it!
All without a warrant, even for local law enforcement.
And why would they bother, when they can just buy it from the#privacy_miningcompaniesthat you already gave it to for free?
