On top of all the controversy regarding unwarranted wiretapping, the FBI is seemingly defaulting on their phone bills incurred during these investigations.
The Office of the Inspector General at the Department of Justice came out with a report on the FBIs telecommunication costs. According to this report the FBI tends to be late in paying their phone bills resulting in their surveillance phone lines being disconnected. The report refers to one case where FISA-related surveillance was halted, and evidence lost, due to an unpaid bill. That's little consolation to those opposed to the agency's wiretapping activities, but it's at least amusing.
Only a summary of the 87-page report is available to the public.
Given the agency's poor handling of their accounts one wonders how well they're managing the volumes of personal data they collect.
