Avira > We definitely don’t have an idea of jail as a punishment in halacha.
right, this would be a reason to try to save someone from a punishment that is too cruel from halachik POV. for simplicity, someone steals in Saudi Arabia or in Soviet Russia – we would not turn him to police that cuts hands off or sends them to Gulag.
> has no bearing on sheltered yidden in eretz yisroel who might not have heard of the past events
Do they know that Mcdonalds are not kosher or do they unwittingly eat hazer there? Even when sheltered, you can learn not to steal and break rules directly from Gemorah. Also, same way community is protecting this kids from assimilation, they should be protecting them from other aveiros. Imagine, a tax-cheater walks in Mea Shearim and kids are running behind him shouting “geneiva, geneiva” the same way they protest shabbos violations.
