Engineers could play a key role in addressing gun violence by developing innovative technology solutions. The document discusses several ideas, such as "smart tech" that could identify authorized users by fingerprints or other biometrics to prevent unauthorized use. It also proposes controlling ammunition through restrictions or technology like 3D printing bullets instead of guns. While some argue that people not guns are the root cause, the document argues that engineering offers a constructive approach to minimize the negative impacts of guns and speed up the process of ensuring public safety.
