Having read January's legal column, it's good to see that the issue of employers enforcing acceptable usage policies (AUPs) has been highlighted. But the issue goes further.

Our investigation last summer showed that many of the UK's WiFi hotspots offer little or no protection from adult and illicit content: 80 per cent allowed researchers to access adult content and bomb-making sites.

It seems that retailers also need to enforce AUPs. They are legally responsible for what patrons are accessing over the web.
