If you carry a cell phone, where you go and how long you are there is captured and recorded.
*sigh*
NO, it is
not.
If you are using a regular phone, only the sites that you use when placing and ending a call are recorded. NOT your location, just the transmitter site that is used. From that, an cellular network engineer (like me) can infer a rough location that is as large as whatever area that site covers. That may be a few city blocks, or it may be many square miles. (Picture the difference between downtown Manhattan where sites are every few blocks, and rural Nebraska, where sites are ten miles apart.) These records are kept for typically 1-2 years. After that, even a subpoena can't get the info because it no longer exists. It's not even archived. There is too much of it to keep it around.
If you are using a smart phone, all of the above, plus every site you use while accessing data. Every URL, every download. That is kept for 90 days by my employer, and it's probably the same for other carriers. It's too massive to keep around longer, and past about 90 days really isn't useful for troubleshooting, which is the only reason we hang on to it at all.
All of the above is available to law enforcement by subpoena. If I access your records without your permission and get caught, I will be fired. Gone. Quickly. One exception - if your phone is causing problems on the network I can look at your data for troubleshooting purposes. If you call into customer service with a problem, they may look at those records to troubleshoot a problem. I can (and do) access the aggregate of everybody's info for engineering reasons, but I don't see individual phone numbers that way.
With a subpoena, law enforcement can get all of the above real time*, and a lot more, including pretty accurate location info, but that requires some special effort. It's NOT happening on every customer. The data would be massive. We don't have the bandwidth to deal with it. And no, the NSA isn't capturing it, either. We'd have to pipe the information to them. That can't be done secretly. Sorry, James Bond is not real.
If you dial 911, the PSAP has your location information. We don't. I could probably set up a special trap and capture it, if I had a reason (can't think of one), but it's actually calculated by an outside company (who doesn't keep it) and just passed through to the PSAP. It's not recorded by us.
Did you choose to let that information about you be captured and used?
Yes, you did. It's in your contract. So there is another reason it has nothing to do with the question of drones.
Your expectation of privacy when using electronic devices is low. Should it be? Net neutrality and freedom ...
"Net neutrality" has absolutely nothing to do with any customer's freedom. It's about managing traffic. That's it. Ignorant and confused people have made it out to be about some imagined "right" to have unlimited data speeds, and how the Evil Big Corporations are just itching to throttle your bandwidth, and Must Be Stopped! (from doing something that is against their own interests and which they have not done in the history of the Internet) but it has nothing to do with anything about privacy.
