Who displays hypocrisy in the novel? How?

Well most of the white characters on the periphery of the novel. Bob and Mayella are pretty messed up. The town, including the jury, have no illusions as to what the Ewell's are capable of. Still they condemn Tom Robinson because of the colour of his skin. The whites go to their white churches but choose to ignore the indignities they place upon the black population. There are a few exceptions, (Atticus, his kids, Miss Maudi) but they are the exception.

Scout's grade three teacher displays hypocrasy during a Hitler and Jews history lesson, whilst she does so Scout seems to be the only one who notice that she believes the Jews didnt deserve such treatment because they're white and blacks in Maycomb diserve what they getting simply because their black.
