I’m not sure if you’re referring to “internet sleuths sit out investigation” or the murder of the executive when you refer to “this,” so I’ll give you both.
The sleuths are basically frauds, at least in terms of any real detective work. They are “finding” middle aged housewives who have seen fit to display their entire lives on social media, before getting filmed spewing some racist rant. “Finding” them is like “finding” a twenty year old on TikTok.
Second, you might believe they haven’t searched for the shooter, but I don’t. No chance. They might be even privately telling themselves that they won’t divulge the name, but I’m not sure I even believe that. They haven’t found this guy because he took a lot of steps to actually conceal his identity, and see #1 above.
With respect to the shooting, the health insurance/claims payment/benefits management system in this country is a complete cluster$&@$. I don’t know the answer and neither do you. But I do know shooting someone in the back on the streets of NYC is not the answer. The schadenfreude so many here and around the country have enjoyed from this, the “well, I guess he got his,” isn’t surprising to (we saw people celebrating thousands of covid deaths, after all), but is instead sort of a reaffirmation of the lack of humanity in people.
