There is a large similarity between Tim Johnson's name and Tom Robinson's. In addition, during Tom Robinson's trial, Scout is often reminded of when her father shot Tim Johnson. For one, after she disbands the mob and is falling asleep, she connects Atticus folding his newspaper and pushing back his hat to face the mob with Atticus pushing up his glasses and standing in the empty street to shoot Tim Johnson. Both are examples of Atticus having to do things he doesn't want to, and facing mindless threats (hence the reason he called the mob animals later). In addition, during the trial, she says that the stuffy courtroom was much like the deserted street that was waiting for Tim Johnson. This shows how Scout is powerless to change the outcome both times. She even goes so far as to say that watching the jury come in was like watching her father go to shoot Tim Johnson, knowing that the gun was empty. The gun can be perceived as the legal process, the bullets as the jury, and the dog as racism, but it could also be seen as Scout's horror at what is happening but being unable to change it.
