Australian Federal Police say Google will face no criminal charges over interception of WiFi traffic in Australia. The plan was to record and to map the names and MAC addresses of WiFi access points. Google, it seems, not only recorded and retained network names and address, but also the contents of any data frames it sniffed as it went by. This means that the search giant ended up with snippets of internet traffic, potentially from millions of users. Googles excuse was that the possibly-personal data it acquired and retained was an accident.”]
