It might be bullshit, but it’s also hardly a stretch. Home invasions do in fact happen, and anybody with half a brain would pretend to have a reason to be there. Door dash, etc make an easy cover that’s not hard to pull off.

That doesn’t support shooting at a fleeing driver or a bunch of other crazy shit in this instance, and it shouldn’t make anybody paranoid that every delivery driver might be there to kill them. The guy with a pizza box walking up your front sidewalk is overwhelmingly likely to be delivering a pizza.
