NewYorkCountryLawyer writes: "The RIAA seems to have a problem making things stick in the Windy City. It has once again backed down in BMG v. Thao, after suing a misidentified defendant. Same thing occurred last October in Elektra v. Wilke. In the Thao case, the RIAA based its case on information that the cable modem used to partake in file sharing was registered to Mr. Thao. However, it turned out that Mr. Thao was not even a subscriber (pdf) of the ISP (pdf) at the time of the alleged file-sharing, and therefore did not have possession of the suspect cable modem at that time."
