What does Exodus 22:1 mean?

If a thief is caught breaking in at night and gets hit and dies, the person who killed them isn’t guilty. But if it happens after sunrise, then they are guilty of bloodshed. Exodus 22:1 - Modern Text Bible

(This rule recognizes self-defense at night, when it’s hard to know someone’s intent. But in daylight, killing a thief is not justified, since the threat is clearer.)
