Some tips to maximise user privacy while deploying this tool: 1) The code, for now, runs locally. This is good. To avoid the possibility of the code being tampered with at a later day (for example, it could be modified to send copies of the image to a server), download the webpage and use the saved copy, not the live copy. 2) Do not use the blur functionality. For maximum privacy, this should be removed from the app…

I’ll just play the devil’s advocate, but when have peaceful protests ever helped the cause? Those are forgotten as soon as they are over.

Of all the civil rights leaders, I’d say people remember Martin Luther King Jr the best. It’s probably also worth asking: when have violent protests ever helped the cause? I think that the violence of the protests helped to get Derek Chauvin arrested. But I’m not sure that continued violence will help the broader movement.

"I have almost reached the regrettable conclusion that the Negro’s great stumbling block in his stride toward freedom is not the White Citizen’s Council-er or the Ku Klux Klanner, but the white moderate, who is more devoted to “order” than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: “I agree with you in the goal you seek, but I cannot agree with your methods of direct action”; who paternalistically believes he can set the timetable for another man’s freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a “more convenient season.” "

A replacement for blur could just be black boxes. Seems easy and safe enough.

"There are _a lot_ of forensic methods to reverse blur techniques" Any examples? You can't reverse it if the data is gone.

Here's a very specific example, having to do with a much smaller data-set, the OCR font used for the routing and account number on cheques. https://lifehacker.com/how-to-uncover-blurred-information-in...

Very minor but interesting nitpick: the font used on checks is not OCR (optical) but MICR (magnetic ink). The design objectives are different and different font families exist for the two purposes. MICR as used on checks (more properly called E-13B) bears unusual, distinctive character shapes emphasizing abnormally wide horizontal components due to the need for each character to have a distinctive waveform when read as density from left to right, essentially by a tape recorder read head. Fonts optimized for OCR are usually more normal looking to humans because they emphasize clear detection of lines instead.

E-13B is a bit of an ideal use case for this method because of the highly constrained character set used on checks and the unusually nonuniform density of E-13B. The same thing can be done on text more generally but gets significantly more difficult.

IF they are identical morally there's still a problem, because they are not identical in power. With power comes a responsibilty to be better than others, and if that's not something you can count on, which it isn't, we need to protect others.

Well they aren't equal, nor has humanity never complained about those in power... Was the police violence worse during the time of the civil rights? Were the protesters ever violent or turn to rioting? What would Dr King say about the protests?

Sibling poster, thank you for the very excellent response

According to Wikipedia (maybe not optimal source), via the PATRIOT Act, groups can be designated as domestic terrorists. I don’t know anything about this topic. Can you expand why you said that there is no “...legal authority to designate a domestic organization as a terrorist group”. I’m no asking about Antifa specifically but generally. https://en.m.wikipedia.org/wiki/Domestic_terrorism_in_the_Un...

The very first sentence of the Wikipedia article you linked to has your answer: "Domestic terrorism in the United States consists of incidents confirmed as terrorist acts." incidents confirmed as terrorist acts . The PATRIOT act defines acts of terrorism. It's on a case-by-case basis. It is not possible to take a domestic organization and designate it wholesale as terrorists. The page also explains that there is no f…

I've heard the 2015 riots resulted in a stand down of the police force in Baltimore, and since then crime in the city has increased significantly. Sounds like the reason criminals are not rioting is because they won. Great for the criminals, but not great for their victims, which are probably mostly the improvished, not the affluent who can afford a replacement for the missing police. In all these riot situations, it…

Leaving aside that the next plea I hear from black Baltimore for more policing on the BPD model will absolutely be the first - I find it odd that you know so much about this, and so little about other things people have said in this thread that you also disagree with. You've asked others to cite their sources. Why be so unforthcoming with your own?

There's the homicide rate, which jumped from 33.8% in 2014 to 55.4% in 2015, and has stayed above 50% since.

https://en.wikipedia.org/wiki/Crime_in_Baltimore#Crime_stati...

A little further down:

"Homicides in Baltimore are heavily concentrated within a small number of high-poverty neighborhoods."

So, my prima facie impression from these data points is the stand down has not benefitted the poor.

Really weird that nobody in the thread is pointing out that this is basically a website that says "give me your photos, specifically from protests, which have details that you want to keep private".

It doesn't matter that it theoretically all happen in the browser. You can serve different versions to different IPs etc. Every heuristic in me would be screaming don't use that if I would have a need for such tool.

Would that be the homicide rate that's shown no significant first-derivative variance from the national rate since 2015? - the homicide rate that you're not even bothering to cite correctly? Those are figures per hundred thousand, not per hundred as you give them here.

In either case, you're massively misrepresenting the "stand down" order, which was not a policy of indefinite disengagement, but rather a specific instruction given in the scope of the 2015 protests in an attempt to avoid further escalation. Whether or not the order was successful in that sense is a matter for separate discussion, but to claim it's a permanent thing, the way you are doing, is simply false to fact - which is probably why you still haven't sourced that claim.

While we're on the topic of BPD actions during the 2015 protests, have you heard about the cop who used the opportunity to loot drugs from a pharmacy and later sell them on to street dealers? [1] I suspect not; for all your apparent interest in the doings of the Baltimore PD, you seem surprisingly ill informed. That's far from all the Gun Trace Task Force got up to, either [2], nor were they alone in their corruption. These are things you need to know about, if you want to talk about policing in my town and expect to be worth taking seriously. But here you are, needing to be told about them. I wonder why that is.
