You can use your phone at a protest if you FIRST clean it of potentially incriminating information, put it in airplane mode BEFORE you even leave your house, AND turn on a passcode rather than face or finger authentication.

@moonman Why turn on airplane mode? I'm seeing some people livestreaming from protests on and such and that has been helpful.

@realcaseyrollins @moonman So you can't be tracked. But, even if it's on Airplane mode, it's probably still logging information. Best to just leave your phone at home, on, maybe running a script that sends messages…and then you have a real alibi. "I was at home the entire time check my digital footprint!"
@realcaseyrollins @moonman Because if any violence or destruction occurs, police can use cell antenna data to closely approximate where you were at any particular time.

@lnxw37a2

just to be clear, close enough but they wont pinpoint it within a few feet or anything. So usually wont be used as evidence on its own.

Still not bad idea.

@freemo @lnxw37a2 @realcaseyrollins Apparently it's possible to radio locate with police Stingray devices, it's not public how advanced this functionality is, though.

@moonman

Stingray devices are more about intercepting messages than radio location.

But any only who has direct control of information from a receiver (such as a stingray device) can radio locate.

Thing is the accuracy is going to be pretty low unless you have multiple receivers.

To give you an idea a single receiver if you know the exact power output of the transmitter will only roughly tell you the distance the transmitter is from the antenna, it wont tell you what direction. With multiple antennas spaces a distance apart from each other (cant all be in one small location) you can start to narrow that down.

So generally they will have a hard time, especially in an urban setting where signal reflections are high, to pinpoint an exact location. But if they just want to know "were you on this particular block at this particular time" they can probably figure that much out.

@realcaseyrollins @lnxw37a2

@freemo @realcaseyrollins @lnxw37a2 The technology gets more advanced every year and there is no transparency on the added features, I would not be comfortable telling someone their cellphone could not be location-tracked at a major protest. Best to assume it is.
@realcaseyrollins cops are known to track and fuck with streamers. That's been going on for at least a decade @moonman
