Which of the following groups is generally considered incapable of committing crimes?

The correct answer is that children under the age of 14 are generally considered incapable of committing crimes due to the legal principle known as "infancy." This principle recognizes that young children lack the mental capacity and understanding to be fully aware of the nature and consequences of their actions. As a result, the law does not hold them criminally responsible in the same way it does for older individuals.

In California and many other jurisdictions, children below a certain age, typically under 14, are presumed to be incapable of committing a crime, also known as being "doli incapax," which means they lack the capacity to form criminal intent. This legal protection aims to acknowledge the developmental stages of a child's cognitive skills and moral understanding.

Other groups mentioned, such as teenagers aged 15-17 or individuals over the age of 60, do not fall under the same legal protections regarding criminal responsibility. Teenagers are generally considered capable of understanding their actions and can face legal consequences. Similarly, individuals over the age of 60 retain their capacity for criminal responsibility unless there are specific mental incapacities or defenses in play. Lastly, educational attainment does not determine one's capability for committing crimes; it is primarily about mental capacity and understanding of lawful behavior.
