Define "theft" under Missouri law.

Under Missouri law, theft is specifically defined as the unlawful taking of someone's property with the intent to permanently deprive the owner of that property. This definition is critical because it emphasizes two key elements: the unlawful taking of property and the intent to permanently deprive the rightful owner of that property.

The focus on intent is particularly important; without the intention to permanently deprive the owner, the act may not meet the criteria for theft. For instance, borrowing property, even without permission, does not imply the intent to permanently deprive the owner, which distinguishes such an act from theft.

This definition provides a comprehensive understanding of what constitutes theft, ensuring that the legal framework targets genuinely unlawful acts rather than incidental or misunderstood behaviors like borrowing.
