The FBI had more than 300 weapons and laptops lost or stolen in just under four years, and some of the computers contained sensitive or classified information, the U.S. Justice Department inspector general said on Monday in a highly critical report. Fewer had gone missing than before a 2002 report in which Inspector General Glenn Fine’s office reported 354 FBI weapons and 317 laptops lost or stolen over the previous 28 months, but he said the bureau had done too little to address the problem.
