The Pells' house is trashed in this scene. This shows us that despite the efforts of the FBI, the Ku Klux Klan has enough strength for it to continue on in Mississippi as well as other parts of the south. Anderson wears a suit in this scene which symbolises a number of things, such as that Anderson recognises that the way Ward goes about things is just as good as the way he does, as Ward is always in a suit.
Aside from this, the people in Mississippi tend to be more casual and perhaps less inclined to wear a suit. In order to fit in with the Southerners, Anderson does not wear a suit in previous scenes. However, the fact he does now hints that he wants to distinguish himself from some of the people in Mississippi, since through the investigation of the murders, he has realised just how cruel some of the people in Mississippi are.
In the film previously, Anderson wore a loose, short-sleeved shirt with no tie. This was his attempt to fit in with the locals gathering information this way. In the Pells' house Anderson is wearing a suit, which alludes to the fact that he is not here to gather information in a subtle way from Mrs Pell (as he previously did), but rather to make amends with her in order to part on good terms.
Anderson and Mrs Pell talk in the kitchen, which is a reference to their previous discussions in the kitchen where their relationship developed and their feelings became more apparent. For Mrs Pell, the kitchen is a place where her husband doesn't go. Therefore, she feels more safe and in control than in other parts of the house, which is why after her house has been trashed, she chooses to go to the kitchen to seek some form of comfort.
This scene underlines the theme of courage displayed by Mrs Pell. She tells Anderson she's "not going anywhere" because this is her "home", she was "born here" and will "probably die here".
Throughout Mississippi Burning we are led to believe that Anderson's method is slightly better than Ward's. However, in this scene it becomes evident that just like Ward's method, Anderson's method has drawbacks too.
Here, Anderson realises that his manipulation of Mrs Pell for information about the Klan has quite possibly left her in a worse situation than before.
Nevertheless, they still part on good terms. We know this because Anderson kisses Mrs Pell's hand and their smiles at each other.
During the film, venetian blinds are a recurring motif of secrecy. In the Pells' house, the venetian blinds have been ripped down, symbolising that secrets are now out.
The next scene is the scene of the funeral. In this scene, black people are singing. The music in the funeral scene starts during the kitchen seen, highlighting Mrs Pells' connection to the black community.
