Before the trial, does Bob Ewell expect Atticus not to try and defend Tom as best because Atticus is white?

In my opinion, the statement above is inaccurate. I don't believe that anyone who knew Atticus would accuse him of not doing his best at ALL times. I think Ewell's first reaction to the news would have been fear. Finch was known to be one of the best..... if I were on the wrong side of the courtroom I'd be nervous..... thus, so should he.
