Then again, what would happen to a protestor that actually protested in a non-violent manner? Let's specify in the US as I can only guess it would be much more dangerous to protest in a country without a protected constitutional right to do so. So a US citizen brings their cell phone to a protest, non-violently marches with their signs, sings some songs, yells some, gets dispersed in a violent manner and/or gets arre…
Their name goes in a file and they get added to various lists. Depending on which list you are on (and who else was at the protest) you will be eligible for further scrutiny. (Remember, everyone breaks dozens of laws a day, as none are meant to be enforced 100%.) Depending again on which lists you wind up on, you may find yourself unable to fly, ineligible for pre check, blocked from a government contract, failing an…
This is exactly why I'm 100% against the idea of using the "do not fly" lists to block citizens from firearm purchases.
Imagine being denied your Second Amendment rights because you went to a perfectly legal political protest the previous year and you're now on a list that you can't get off of.

I'm also glad you did that, we need more more people like you.
Did you miss the part where he is replaced by someone with little to no ethics or morals and will implement whatever is asked without second thought?

#195I remember this being described in Bruce Schneier's book. When I first read it, I was terrified. Now, seeing them in action, I'm closer to dejected. Most methods of avoiding them aren't easy or practical enough to be used by the layman, hell, most laymen don't even know what stingrays are. These are incredibly tough to protect against on a mass scale.
What happens when they are used in countries with fewer protections to individuals than the US?

You should not have to be good at opsec or economically advantaged to be able to demonstrate.
Then don't bring a cell phone to a protest?
Cops can still come and harass you by coming to your house if they can find you or you filmed something they don't like. One person who filmed apparent police violence in seattle had 5 cops come to his to arrest him for something random about another protest. They may have found him from the account he posted it on. In either case, there will be attempts to find some people who weren't involved in violence.

That is correct. The phone waits until it has enough power to ensure it won't die during startup because a lot of modern phones (and ultralight laptops) require tapping into battery reserves because the direct pathway from the wall wart to the device was not designed to provide sufficient power to operate at full speed/capacity for more than a brief turbo boost and startup requires more than that.
Battery charges "enough" to that point in less than a minute? I find it hard to believe. 4-5 minutes? Absolutely. 50 seconds?
I suppose the timing depends on if you have one of the anemic iphone ones or a full 2.4+ amp USB charger. Given that charging status is unreliable at low charges and charge tends to "come back" a bit when not actively drawn.
My current phone has an old battery and can go directly from 40% to 70% charge in one refresh cycle (10-30 secs?) after plugging in to my ikea charger.

#198Pro-tip: If you want fairly good OPSEC when going to a protest, get a burner Android phone, put it on airplane mode with WIFI only. Then purchase a couple of Comcast / Xfiniti logins off the web, and use those to connect to "xfiniti-wifi" hotspots. Most cities have them, the speeds are fairly decent too. We're truly living in the panopticon
Won't your wifi mac address be a unique identifier? Did google start doing wifi mac address randomization?

If you have gapps installed (every stock ROM unless you're in china), you should probably assume google is tracking your location through wifi networks. As such, you should probably install lineageos for additional security.
This is more reason then ever to flash a generic android image. Google does track your wifi and have amassed a huuuuuge library of SSID name, freq, mac addresses and this is what they use alongside IP geo location for google maps and other services. It's good and also bad. And if you restrict these things, you "look" like a bot so you have increased friction to accessing information! The looking like a bot, makes sen…

This doesn't really exist. It's not like a Linux distro, each specific device requires a specific device-tree, a separate image. postmarketOS and others are trying to change this.

How is this possible?
You can use a non-linear junction detector, and triangulate on the signal it forces the target radio to give off. They are not very selective, so it’s easier to track when there are very few radios in the area under illumination. The easier way is to compromise the phone and have it pretend to be off.
Does the first method work if the battery is removed?
Could the non-removable battery "feature" of newer phones be a result of governments requiring the manufacturers to do this?
