I'm told that my grandfather had a favourite saying: "A dead horse can't kick you." Meaning that if he's kicked you once, don't give him a chance to do it again. Now, I'm not a zero tolerance kind of person but, this case makes me think twice.
A synagogue in Toronto was sued by a married woman in her early 50s who claimed that the cantor (who leads the prayers) had enticed her into a sexual relationship. Once this was publicized in The Toronto Star, a second woman came forward with a similar story.
Here's my point. The synagogue knew about the first offence but kept it secret and gave the offender a second chance.
