Last month, the police chief of Lincoln, Nebraska announced that the security cameras watching over the city’s downtown bar scene have not proven effective in his department’s efforts to stem criminal activity. Police Chief Jim Peschong said that the recordings hadn’t helped investigators either identify new suspects or bolster evidence against current ones. Peschong also stated that the cameras hadn’t lowered crime in their vicinity: according to Lincoln Police statistics, there were 128 assaults within 500 feet of the cameras last year, numbers that are on par with the department’s five-year average.

Federal agencies served with a Freedom of Information Act request are refusing to release documents related to their purchase, use and disclosure of zero-day exploits, keeping the American public in the dark about a practice that leaves the Internet and its users less secure.
