👉 A non-vigilant person, or a non-penetrative individual, is one who does not actively participate in an activity or endeavor. This can be defined as someone who is passive rather than active, and who does not engage with or contribute to the activities of others. In the context of law enforcement, when referring to a non-vigilant person, it means someone who does not actively participate in a specific task or procedure, such as being present at a crime scene.
