I want to comment on what someone already said.
The comment was upset at treatment of Jewish practice portrayed in the film. However, the rules on adultery and trials, well ... if you want to be upset, be upset at the gospels.
The gospels portrayed the trial as a crooked rush job. Likewise, the stoning for adultery (and in the past, rural areas did not always strictly follow the dictates of the law) was referenced in a favorite scene in the Bible as well. The Bible had no "backstory" underlining that really the stoning in practice was a last result and rarely done practice. We were meant to see it as barbaric, the crowd driven more by passion than reason (before Jesus came around to guilt them).
In fact, some gospels had various scenes that put Jewish practice in bad light. At times unfairly. For instance, the money-changing in the temple -- you needed that to allow people from all over to have the right sort of coin to give their offering. It surely had some bad flavor, but it was not just about a "band of thieves." Lashing out like Jesus did kinda suggests why some thought the guy a tad bit dangerous especially in an age of rebels and revolts.
If one wants a "historical" reflection of what "actually" happened, which honestly would be not a bad way to go, they wouldn't be as reliant on scripture and all. The conceit of this movie also would not really be possible, to be totally honest about it.
