I see what this comment is trying to do, but I'm not sure what the author thinks this comment is going to achieve. Many if not most hacker news links are going to leave someone unhappy; it is the nature of hacker news. Either a navel gazing techie is confronted, or a victim of tech myopia does not receive justice. As we know, unhappy people are more likely to leave a comment than happy ones, so if this comment is actually read by people, most people who read it, regardless of their IQ, will just dismiss it as written by someone who probably doesn't care about police accountability in any form.
As this comment will have no bearing on whether the website will have its intended effect, whether anyone uses the website, whether public records of negative interactions will spur reform, or anything else, all this comment really does is serve as a platform to shit talk the website. Now, there are definitely some websites that deserve to be called out for not achieving the effect of full scale, immediate nationwide police reform, but commenting about it on Hacker News really won't do any good.
