Lethal weapons are tools or devices designed to cause death or serious injury. They can include firearms, explosives, and certain types of knives. The primary purpose of these weapons is to incapacitate or kill a target, making them a significant concern in discussions about violence and crime. The use of lethal weapons is often regulated by laws that vary by country and region. For example, firearms may require licenses, while explosives are typically restricted to military and industrial use. Understanding the implications of lethal weapons is crucial for public safety and law enforcement efforts.
