Georgia lawmakers may require that every public school student be checked for weapons each day. On Monday, a Senate committee advanced a bill, pushing it closer to final passage. The proposal follows a 2024 shooting at Apalachee High School in Winder that killed four. Supporters say detectors will help spot guns and knives. There's little research, though, that their broad use stops school shootings. There are also concerns about how much the systems cost, how to guard against false alarms, and whether detectors are really needed in elementary schools. Some opponents say the state should limit kids’ access to guns instead.
