Why doesnt mrs logan punish the kids for going to the wallaces store, and why does she take them to see mr. Berry

A man named Berry was almost burnt to death by white men. Stacey says that Mr. Lanier had fetched Big Ma to help nurse Mr. Berry the night before. TJ knows about the burning because Mrs. Logan had stopped by to talk to his mother about it before school earlier that morning. The Wallace family would have been involved with this. Mama wanted them to know what the Wallace's stood for.
