Thanks Yosef, you posted this as a reply. I deleted it and made a new topic out of it and added some rashi.
I am finding this interesting, because we're talking about a group of people that are largely rattled, in that they have been recently freed from slavery and a long exodus where lots of people died (and were born) were led to a land, taken away... These people don't really have any self identity and at this point, they are probably happy to just not be slaves. Now, we're talking about setting up a society and legal system. So in this parsha, when we talk about such a system with
שופטים ושוטרים we're talk about police and judges. My question is, how can one be an expert judge as rashi says, since no one has any real prior experience and we're building a society from scratch ?
