If you leave your wallet on the ground in a park in SF, the chances you’ll get it back are probably pretty high. If you leave it in your locked car, your car will probably get broken into. Thieves are strategic. They’re not looking around in parks for lost wallets, nor are they going to libraries hoping they can lift a bunch of unattended books.
Career thieves wouldn't scour a park for wallets, no, but many people are opportunistic thieves. If they happen upon money with no one in sight, they'll just take it, without thinking it's a big deal. The case in the article matches the second model, not the first. Hundreds of people realised they were in a library with no staff. Two-hundred books were taken out, presumably without anyone having to log their names. T…
The article states that every book taken out was returned. I see two alternatives:
1. The staff conducted a full inventory a couple of weeks after the incident and confirmed that every book is still there. (By the way, at what rate are books smuggled out even during regular opening hours?)
2. The books that were taken out were borrowed against a library card using some sort of self-checkout station.
I find option 2 much more likely, which meant the names were logged.
