‘Now don’t you be so confident, Mr Jem, I ain’t never seen any jury decide in favour of a coloured man over a white man…’

This sentence reinforces the racial prejudices in the story and has significance to racism in the 1900s.  Black people were extremely discriminated against during this time and as a result nobody took their side in a court case. Black people were usually convicted of crimes they didn’t commit because of their skin colour. People, like Atticus's character, would try and defend them but the white people couldn't see past their predjudice and there was no hope for any of the black people.  

The evidence and facts that Atticus was coming up with was suggesting that Mayella’s father was her abuser. But even if this was the case, he would never have been sentenced because he was a white man against a black man.
