The protests were sparked by the lack of accountability of the police resulting in police brutality. The violent people among the protesters are subject to the same incentives. The more they expect to be held accountable, the more likely they will refrain from violence. Anonymizing photos of the violent ones is therefore likely to support their actions by making accountability less likely. To scrub ethically, limit i…

What's your plan, exactly, for making the program not work for you if you've smashed a window?

To add though: it's not easy to tell who are the non-violent and who are the violent protestors. Sometimes violent protestors hang out in the crowd and only strike at opportune moments. If they're blurred out like everyone else during the times they are not violent then it becomes harder to hold them accountable.

How resilient is blurring against deconvolution?

> How resilient is blurring against deconvolution?

This depends a lot on the implementation details. If you blur an image using arbitrary-precision real numbers, then blurring is invertible. If you add a bit of random noise, or quantize your pixels into a finite-precision data type, then it becomes essentially one-way, and you cannot recover the original image.

Given that this is a protest about cops getting away with brutality even when there's clear evidence I think "gather evidence against both sides equally" is unlikely to be convincing argument to protesters.

I recently found myself in a position where I had to blur a ton of faces from multiple pictures (about 100/day). It’s really tedious to do it manually and something like OpenCV shines. We found a repo [1] with python code that automatically detects and blurs faces. This script was one of many, except it had a very high accuracy. Over 90%. Removing exif data is a great idea.

There is also the PixLab API which let you automatically apply a blur filter for each detected face or any other target regions you want using only two Rest API endpoints.

This is great for some situations. However, my personal policy is to upload my protest content to Google Photos asap (if appropriate). This makes sure your content is off your device if your phone gets confiscated AND it provides (be it thin) layer of authenticity/validation of the content.
