I was curious about that comment so I Googled it. Here is the top hit which has fairly good depth: https://sanfrancisco.cbslocal.com/2016/05/14/shoplifting-california-prop-47-reduced-penalties/ https://sanfrancisco.cbslocal.com/2016/05/14/shoplifting-cal... The summary seems to be that Prop 47 treats shoplifting under $950 of value as a misdemeanor. As a result, law enforcement is unlikely to pursue and punish, so thieves get away scot-free. Additionally, organized crime has exploited this and can easily recruit people for their shoplifting rings. The article reports that retailers have seen a rise in shoplifting since the law took effect. So presumably, package theft of anything below the value of $950 from a door step (not a federal USPS mailbox) would only be a misdemeanor in California.
