these days all a man has to do is move to another community

It's pretty unlikely he won't be recognized.

Do you think the bail agreement/amount for Sam was appropriate? Too high? Too low?

Doubt.

The Jewish community is tiny, maybe he could do it for a short time, but the chances of no one recognizing him is zero.

Unless he didn't move into a Jewish community, but then he basically self-shunned himself.

(And there are not thousands of communities, certainly not in the US.)
