It is also true that people who rob businesses are harmful to society. That is completely independent of the terrible outcomes caused by private vigilanteism.
I see, but I don't find a problem with that either though.
Seems no different than crime stoppers, it's usually just a reward for information leading to an arrest, it's not an actual bounty. It's not excluding that, but he's most likely hoping someone who knows the person who stole it will rat for the money.
And I think you'll have to provide examples of the "terrible outcomes caused by private vigilanteism".
the guy confronted him and held him there until the authorities arrived.
are you implying people should not protect their livelihood and let trespassers loot even if they could stop them?
why should those property owners who are fully in the right morally and legally do that when the trespassers are flagrantly breaking the law?
