Location data for sale... "FCC can't punish us!"

So let’s say Jeff a serial killer goes to his victims house and hacks up his victim. He brings his phone with him in case of an emergency.
He gets arrested for reckless driving. They find a body part in his pocket.
Can the police legally use his phones data to track where he was in the past?

The simple answer is "yes" - but as of now, the police will have to pay the ISPs for it... "justice as profit".

Privacy is void where criminal action is concerned. 
The commission of crime instigates investigation, privacy is not a barrier to it.
It's part of the covenant you adopt when you set out to kill, steal, harm... crime is a "come what may" thing.

But this association of crime with privacy seems weak. 
That association could rightly justify that privacy leads to crime, or that privacy IS a crime!
That is the hyperbolic ending of our disconnection with privacy as an element of human dignity.
Bad behaviors happens with or without privacy, why should it be privacy that gets amputated if it does not stop, or even address, the bad behavior?

Further, this is not about the bad behavior of people whom we judge "shouldn't have privacy," this is about privacy as an element of the natural state of social existence.
Will those raping your data for their profit posture as "protectors" of society now?  And charge you a fee, no doubt, for the service? Or charge authorities investigating crime?  Are they to be the 'gatekeepers' now?  "Selling" something they haven't created, or even compensated the creator for?  Allusions of slavery again.

Information that exists in direct relation to me, who I am, where I am, what I do (or even think)... that is NOT low-hanging fruit for anyone to exploit... except ISPs in America it appears.

And we, as users of the Internet, have we any say whatsoever? 
Can we object, if so to whom? 
Apparently, the only people who object "haven't the 'legal' authority to do anything." 
Apparently, complaining directly to the abuser is only a joke, a profit opportunity for lawyers, an exercise in whining about things you can't change.

There are two kinds of blindness in the world, people who can't see; and people who can see, but won't look.

Privacy is more than a 'convenient' 'no-matter' triviality... it is a foundational element of personal freedom from which liberty becomes real.
