What does Judges 20:6 mean?

So I grabbed my dead wife, cut her body into pieces, and sent those pieces to every part of Israel’s territory. I did it because the people of Gibeah committed a crime so brutal and disgusting that it shocked all of us. Judges 20:6 - Modern Text Bible

(The speaker explains his shocking actions as a desperate way to show all Israel the horror of what happened in Gibeah. He wants everyone to understand the seriousness of the crime.)
