He actually tried calling the city to ask what he should do with abandoned laptops. He was transferred multiple times, told to call multiple numbers, and tried leaving voicemail messages to find an answer. He got nowhere, and the closest he got was "That's a good question".
The law explicitly states purchased laptops, which he did not. Now we can say "But that's not the purpose of the law, just the letter!" But the purpose of the law is to make selling stolen laptops non-profitable to thieves - and abandoning them does not turn a profit. Meaning Louis runs afoul of neither letter nor spirit of the law.
And so I'm legitimately asking, if you think he's in the wrong: what is he to do, when he can't properly fill out LEADS online without a purchase price? He tried calling the city, he tried calling would-be customers to collect their things. The former couldn't tell him, and the latter told him it wasn't worth their time.
