This is the Walgreens video that was shown on my news. This shoplifter had a whole trash bag that he filled up with stolen goods.
I don't know what the law is is San Fransisco, but here, security guards can't confront a shoplifter once they leave the store. Even if they see a person walk out with stuff and have it in their hand. The guards aren't police officers, so they can't stop thieves once they've left. And for various reasons cited in another post, many guards are hesitant or aren't allowed to stop theives in the store. They are mainly there to show a presence, or if a
major crime is happening.
We used to hear those alarms go off all the time by the front entrances as people stole stuff, and we asked why aren't the guards going after them or stopping them? Just like in the video above, when shoplifters knew the law, they walked out or ran out with stuff all the time. Now, I think most stores just have the alarms to stop honest people who willingly stop and open their bags. They get the item re-scanned and the security tag deactivated.
