As far as I have been able to determine, this is the first time in the US that a law enforcement agency has attempted to do this, and although the courts have generally ruled that running an open wireless network waves your expectation of privacy, it feels like this is setting an extremely bad precedent for law enforcement going forward from here. The AustinEFF has filed an Open Records request against APD (Austin Police Department) for information on the details behind this operation, http://effaustin.org/2011/09/austin-police-department-announces-operation-wardrive/ . My primary concern is, at what point in time does your SSID give probable cause for an officer to connect to your network to conduct a search for "illegal" content? Though the EFF's concerns are more varied than my own at this point."
