Yes! It’s an olympics game of mental gymnastics where everyone - BestBuy, DoorDash, OP, the police - try to offload responsibility onto someone else. However, a crime WAS committed. Someone is the victim. The victim is the one who was deprived of property/money and will not have access to it until/unless the thief is caught and property recovered. BestBuy thinks OP is the victim, since the item was stolen off (not)their porch. OP thinks BestBuy should be the victim, since OP had no involvement in organizing the delivery. DoorDash could also take up responsibility of being the victim, since it was their (not)employee that stole from them.
If OP goes to the police now, they would be losing the mental gymnastics by accepting the status of the victim. BestBuy would never refund them in this case. It is in OP’s best interest to pursue the chargeback first. If OP succeeds in the refund or the chargeback, then BestBuy will have no package and no money, so BestBuy would be the victim. Then it will be BestBuy’s responsibility to report the crime.
I agree that OP is in the best position to report the crime to the police - they are closest to the police station, they have video evidence, they literally know who the thief is - but it should not be their responsibility! OP has done nothing wrong and there are no measures they could have taken to prevent this crime (other than not shopping online at all). If OP gets a police report, OP is taking up the task of being the victim, and then BestBuy has no legal obligation to refund them at all, other than out of the kindness of their heart. Rather, BestBuy is the victim in this crime, same as if the item was stolen off the shelf at their warehouse and scanner records forged. It is their responsibility to file a police report, if they want the numbers in their system to add up. Only then could they ask OP to kindly provide the video evidence to help them out, and they’d be lucky if OP would give it to them, having no obligation to do so.
