The Gateway Pundit is trash. (Just read this article about George Floyd to see how badly they can twist facts into absurd conclusions. George Floyd was murdered by police. That's objective fact clearly proven by video.)

Here's a less sensationalized version of the story in the OP: https://fox59.com/news/crimetracker/indy-mother-becomes-2nd-homicide-along-downtown-canal-in-1-week/

There was no "mob", just two groups of assholes who encountered each other and went as far as flashing guns. It started over "a slang version of the N-word" (nigga?). There's no transcript of what was said but based on the known circumstances, there were no heroes here.

Obviously this murder should still be punished - an ambush with a gun is damn cowardly, too - but OP's headline is very misleading. This happened at 3am between two armed groups that got into an argument over race.
