TKAMB chpts 17-19

These chapters are important because they bascically help prove Tom Robinson truely is innocent... If these chapters didnt excist, and we werent sure if Tom Robinson was really innocent or not, the book would be pointless, because there wouldnt be something worth fighting for.. Heck tates story is straight, but it contridics mayellas, and it shows that the stories or unacurate... Without these chapters also, the ending of the book would be insignifigant, because Bob Ewell wouldnt have a reason to come after jem and scout and boo never would have showed up
