Local business uses Facebook to catch shoplifting suspect

I do not know the legality of this under Australian law, but it's certainly the future.

A small business in the US put a picture of a suspected shoplifter on their Facebook page and asked their followers to help identify the suspect.

Their Facebook followers started contacting them within an hour; she was soon identified and shortly thereafter, was in police custody. The days of an anonymous shoplifters maybe over.
