Delivery rep work is pretty dangerous, same with Uber drivers and other gig workers. Since you are not an employee, companies have no incentive to ensure your safety. You go to unsafe neighborhoods all the time, and risk of getting jumped in always present. And as I said, cops get leeway for far more egregious shooting, so why should this guy be hanged dry?
And I’d invite you to watch a few “prankster” videos on YT. Most of these are spoiled brats who are always trying to up the ante video-over-video. There is a deliberate attempt to intimidate and confuse their victims. So yeah, they had it coming.
