I don't believe in justice.

I believe in consequences.

We either create a society that favors positive outcomes or we don't.

When we don't we end up with too many negative outcomes, which feed into more negative outcomes like a vicious cycle and then everyone has a bad day.

Too many grudges yields a high rate of terrorism, which in the US looks like rampage killers with assault rifles. Also a shitload more of suicides; we're really not that confrontational as a society.

So far, this still looks like a pro hit. The suspect is still at large, where novices quickly get located. And they knew their way around their weapon, clearing a jam neatly mid-encounter.

It could be revenge for denied coverage, but it smacks of something more personal, a rival or enemy or someone who wanted him dead not for revenge, but out of the way, say a power grab.

It's a guess based on too little data, but it smacks more like Göring deciding to eliminate Röhm.

However, Charles Dickens is still right. If you forgo humanity in persuit of wealth, the public will cheer your demise, whether it is by gunman or crush depth pressures undersea. Today's revelatiob is less that a rich guy died, but that the public is delighted by the news of the incident, and has little shame about it.
