What can justify the use of non-deadly force according to legal standards?

The use of non-deadly force is justified under legal standards when a person is lawfully present and is preventing unlawful intrusion. This situation often involves a reasonable perception that someone is attempting to unlawfully enter or interfere with one's property or safety. The law recognizes that individuals have the right to defend themselves and their property from unlawful threats or intrusions, as long as the response is proportionate to the threat faced.

In this context, being "lawfully present" implies that the individual has a legitimate right to be in that location, and preventing unlawful intrusion is a necessary measure to ensure safety and protect property. The application of non-deadly force in this scenario must also be reasonable and necessary to stop the threat, aligning with the principles of justified self-defense and defense of property.

The other scenarios do not meet the established legal standards for justifying non-deadly force. For instance, simply feeling threatened without an actual danger does not justify a forceful response, nor does attempting to escape from a crime scene or defending someone else without a legitimate threat. Thus, the context provided in the correct answer reflects a clear legal basis for the use of non-deadly force.
