Yes, but scamming is still illegal. Shard KNOWS who scammed him, and got photographic evidence of it in action. I'm pretty sure, knowing the criminal's name and information in real life would allow the cops to persecute, trial, and punish.
Being a social issue, this would indeed fall under common sense. It's just like abusing full trust to scam someone out of money, which I've noticed also falls under the common sense rule, and is being forced at current. What difference does it make?
Shard has been scammed by Jasa for having placed trust in him, so he reports the crime to the officials. The officials deny ALL of his evidence and dismiss his case on the factor that he had placed his trust in the wrong man. This isn't justice. The criminal remains spoiled with the victims money untouched, while the victim lies helplessly without any sort of aid to his woes.
I am not over-comparing this to life itself, because being a social issue, there's no difference. It's just as morally wrong as it is in real life.
