Final answer:
Barney committed embezzlement by taking toilet paper rolls from his workplace without paying. Embezzlement involves an abuse of trust by someone entrusted with property or funds.
Step-by-step explanation:
The type of larceny-theft that Barney committed, by taking a dozen toilet paper rolls home from the retail store where he works without paying for them, would be classified as embezzlement. Embezzlement is a form of property theft that occurs when someone who is entrusted with money or goods appropriates them for personal use. This differs from shoplifting because Barney is an employee and not a customer, and he has violated the trust placed in him by his employer. While embezzlement is often associated with large sums of money, it can also apply to smaller thefts like the one Barney committed.
