Which of the following substances is NOT considered a lethal weapon under ACT 235?

The correct choice identifies chemical mace as not being categorized as a lethal weapon under Act 235. This distinction is primarily due to the nature and intended use of chemical mace, which is designed for self-defense and incapacitation rather than causing lethal harm. While it can certainly cause serious injury or even death under certain circumstances, it is classified more as a non-lethal or less-lethal substance compared to the other options listed.

In contrast, firearms, batons, and knives are typically classified as lethal weapons because they have the potential to cause death or serious bodily injury when used as intended. Firearms are explicitly lethal due to their design for inflicting substantial damage, while batons and knives, though they may vary in lethality based on usage, are still considered tools that can result in death or serious injury.

Understanding the context of how these weapons are typically used and their inherent danger is crucial when analyzing their classification under Act 235.
