The nation’s largest maker of bulletproof vests is urging police agencies to replace nearly 100,000 vests that could fail and result in “serious injury or death,” reports USA Today. Chance Body Armor of Central Lake, Mi., said testing of Zylon, a fiber used in the vests, indicated that it can degrade suddenly and cause a dramatic loss in the vests’ ability to stop bullets. The warning comes two years after Second Chance recalled 130,000 vests, partly because of problems with Zylon.
At least nine states have filed lawsuits against Second Chance. Second Chance has said that there is no definitive evidence that a failure of one of its vests resulted in an injury or death. “We are concerned that officers would remove the vests because they have no confidence in them,” said Joseph Estey, president of the International Association of Chiefs of Police.
