You won't get "briefly detained and released the next day" if you're caught doing the same thing every other night. And the sentence you receive in the end will be far more severe than if you only committed the one initial offense. Penalties and fines will likely erase any money you made on other nights. And oh maybe an investigation is opened to find out who has taken all these scooters, now that 50% of the time you don't get caught in the act means little seeing that you're just getting caught after the fact.
