I don't know about #11 being ISTJ- I would have said INFP actually. He has some very strong values, causing a normally meek, friendly man to get angry at 7 when he changes his position. Plus, I personally identify with the way he shyly gets up at some points to awkwardly state his opinions. And then there's his speech after the blow up between 3 and 8 in the middle, where he insists they don't all fight.
#9's an interesting one. I thought from the way that he vividly recalls the details of the way the witnesses looked and dressed (especially with the memory of the marks on the woman's nose) he would be an S. But then the way he theorizes about the motives and personality of the old man who testified to hearing the boy shout makes him sound like an N. Hmm, I'm confused.
Yes to #7 being ESTP, not so sure about #1 being that too. Just not sure.
And the others I can't be bothered with right now. And this post is probably long enough.
As one might guess, I also really love this movie! (My favourite old b&w movie, ever. )
