Reminder that in the US, police are not legally required to protect people or property from crime. If the officers are not assured of their own safety they will just sit and watch, and no one can hold them responsible for that. So all the taxes you pay to fund the police department all year are buying you basically squat.

And again all the above assumes you not the exact power output of the transmitting device. When you have power output that adapts and therefore is unknown you need even more receivers.

@moonman @realcaseyrollins @lnxw37a2

@realcaseyrollins @adsb Yeah, but if the world went to shit and all our infrastructure collapsed you could still run a radio station and communicate with others over the airwaves if you had access to like a generator.
@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.

@freemo
Yeah, I just don't think they are largely rioting against other whites. They are not targeting whites per se (how do you recognize if its a white shop or black shop?). A saw a lot of videos of burning police cars and stations, big companies. I know it's mostly anecdotal, but right now we can only guess.

Can there be some people who are racist for sure I just dont think its the overall trend.

There is a large portion of the right who see blacks as a "bad race" and that includes fellow blacks.

@realcaseyrollins

Unless we accept that people can be angry at their own race, which seems to be largely the case, and to some extent id even say its justified given the history of whites in america.

Some scary footage from our friends in America.

Be safe out there. #BlackLivesMatter

National Guard marches through a quiet residential neighborhood in #Minneapolis, screaming at citizens to get inside.

Soldiers stop to point their guns at residents on their balcony.

They yell “LIGHT THEM UP” as they fire riot control rounds at them.

@jeff

they use triangulation, a tad bit more than trig as the antennas are generally not highly directive (they are partly directive or omni).

If your really curious I can run you through the math though.

@realcaseyrollins @lnxw37a2 @moonman

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

@vnarek

I think there is a large portion of those rioting and looting who are white. But even they were largely rioting against other whites.

There is a large portion of the left who see whites as the "bad race" and that includes fellow whites.

@realcaseyrollins

@freemo
Again, I disagree with the "largely by race" take. Both races rioted together, looted together. I would say it's a class thing and sadly the upper class is more white.

I don't understand why it's a class thing too. Maybe if we add up the pandemic deprivation and economic situation of the poor it would make more sense.

In my opinion they are multiple groups pushing multiple agendas.
