Timely article, but what about violent criminal activity during protests? Peaceful protests are wonderful and have been very effective throughout history. The protests we've seen for the past few days are not helping anything. Yes, people are angry at the criminal behavior of the police officer/murderer, but manifesting that anger by destroying property, looting, injuring, and threatening others, is only going to jus…

I think its root is in "direct action"[0], and intentional/encouraged by at least some. Others are just opportunists, for their own gain.

“Getting away with” Who is getting away with what? They are under arrest right now. Or do you want them dragged through the streets?

> They are under arrest right now. One of the four officers is charged. With a lesser charge than some are calling for (third-degree instead of first-degree murder). I don't think the other three officers are under arrest right now. Some people regard them as involved and getting off too lightly so far.

First-degree is premeditated. Third-degree is depraved-heart ("murder as a result of callous disregard for the value of life"). What evidence supports a first-degree charge? If you want him to walk, charge him with first-degree. Good luck proving premeditation beyond a reasonable doubt. The depraved-heart charge is a slam dunk, and is clearly the right one if you actually want justice.

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

> You can't reverse it if the data is gone. That's the problem - the data you think is gone isn't gone. High frequencies are gone.... but you left all the low frequencies, didn't you? You can read a face from the low frequencies.

If you blur then mosaic, or vice-versa, then presumably you get rid of the low and high frequencies? Depending on the detail shown in the original image either, or both, might remove enough information to render the image anonymised.

How about replace each face with a "this is not a person" AI generated face, then blur+mosaic. Or just a non-person face using a deepfake system that matches the facial expression?

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…

The data isn’t usually gone, just spread out!

Even more impressive, you can see around corners with similar reconstruction techniques

When I hear your first point, I consider the possibility that these are not retaliatory murders, but rather ways to keep something secret. If there was an agenda behind these riots organized at a higher level than these leaders, similar to what is being suggested by some during these current protests, and those higher level organizers wanted to keep the agenda or those who set it hidden, it could explain why lower le…

Here's the thing about "black swans". If you ignore "white swans" in your hunt for black swans, you're going to miss a lot more swans overall.

Ok, so don't ignore either. You can consider multiple theories at once.

As of today, the president is designating antifascist protestors as a terrorist organization.

The "president" has his thumb up his ass, because that's actually not a thing he's legally able to do.

Neither is there a domestic terrorism statute, nor is there any legal authority to designate a domestic organization as a terrorist group.

So, even though the "president" is pro-fascist, he's really still got his hands tied there.

So based n all the replies, can someone design the most resilient facemask that can never be understood by facial AIs?

First degree is harder to convict, better to send him to jail for a crime he clearly committed than for one we hope we can make a strong enough case for.

If he was charged with first degree murder, he would walk if the high bar was not met.

For the record I agree with you, I'm just saying strategically it is a smarter move to ensure he is convicted for his crimes

All you need to do is watch videos of protests anywhere to see cops aggressing on protestors, shooting people on their lawns, arresting and shooting reporters for major news networks on camera. When people are aggressed upon by armed security forces in other countries I'll bet most dont take the side of the people with the guns, so why now?

There are examples of pure looting. E.g. The Grove in Los Angeles: https://youtu.be/hpXdXLaJhKE

Ugly but beside the point. Why arent the police protecting these businesses, if looting is such a concern, rather than instigating peaceful protestors? Besides, these businesses are all insured; Im certain that Apple and Luxottica, some of the richest companies in the world, can write off the loss.

By contrast, nothing will bring back George Floyd, let alone the countless black people afflicted by police brutality that weren't caught on camera. With millions still unemployed and a sense that society has left so many behind, COVID in the US was a powder keg looking for a match, and a breakdown of order shouldnt really be unexpected.
