I've never understood that, the suspect's motive I don't think has any effect on the case. And why should a suspect share the motive? Why do police want to know the motive?

For starters, someone should only share their motive if they're going to admit guilt. If they're just a suspect and they're trying to maintain an innocent status then it would be stupid of them to give a motive. But as for a guilty party giving their motive, it can help them if they have a sympathetic reason for committing the crime. For instance with a "crime of passion." A judge or jury is more likely to go easy on you if you killed your spouse because you caught them cheating on you as opposed to killing them because you just didn't want to be married any more.0
