Section 23 of the Theft Act 1968 states:
Advertising rewards for return of goods stolen or lost.
Where any public advertisement of a reward for the return of any goods which have been stolen or lost uses any words to the effect that no questions will be asked, or that the person producing the goods will be safe from apprehension or inquiry, or that any money paid for the purchase of the goods or advanced by way of loan on them will be repaid, the person advertising the reward and any person who prints or publishes the advertisement shall on summary conviction be liable to a fine not exceeding [level 3 on the standard scale.]
It seems like its main possible effect would be to criminalise the most desperate victims of theft. What could be the likely logic behind it?
