A boy's hand was blown off. That single catastrophic injury has forced France to suspend police use of stun grenades, a decision announced after several advocacy groups accused law enforcement of wielding disproportionate force against teenage protesters. The weapon that maimed him had been standard issue. The suspension marks a sharp reversal in crowd-control policy, coming amid broader scrutiny of how French police engage with young demonstrators. Multiple organizations had lodged formal complaints about the tactics used against teenagers in recent protests, though the specific incident involving the boy's injury appears to have catalyzed immediate government action. Stun grenades—designed to disorient through noise and flash—can cause severe trauma at close range. French authorities haven't detailed whether the ban is temporary or signals a permanent shift in policing doctrine. The complaints from advocacy groups centered on a pattern they described as excessive: weapons designed for riot control being deployed against school-age protesters. What happens next depends on whether France treats this as an isolated equipment failure or a systemic problem in how it polices dissent among the young.
