The age at which a child is considered capable of acting responsibly.
Under Common Law, seven was the age of reason. Children under the age of seven were conclusively presumed incapable of committing a crime because they did not possess the reasoning ability to understand that their conduct violated the standards of acceptable community behavior.
Those between the ages of seven and fourteen were presumed incapable of committing a crime, but this presumption could be overcome by evidence, such as the child having possession of the gun immediately after the shooting.
Children don’t reach the same milestones at the same time. He’s just a kid, a kid who needs guidance, but just a kid.
