No, people paid him for something, he didn't provide the service, and he hasn't refunded the money. That's called guilty!
That means guilty of making bad business decisions. Doesn’t say he’s a straight out thief ?
He paid deposits (even to hotel and maybe to scammer ) so how should he pay back something he doesn’t have ?
Bottom line is nobody showed 100% evidence that he is guilty.
Anyway to contact his friend who sponsored his pesach in South Africa ?
Or to see when he bought those tickets ? Was it bought before or after program was cancelled ?
