Which of the following is NOT a sign of illegal entry into a property?

Choosing "secure windows" as the answer is correct because secure windows indicate that the property is protected and has not been unlawfully entered. Signs of illegal entry typically involve evidence that suggests a breach of security.

Pry marks, lights being turned off unexpectedly, and ladders or other means of roof access are all indicators that someone may have tried to enter the property without permission. For example, pry marks suggest forced entry through doors or windows, while lights that are usually on being out might indicate a disturbance or tampering in the property. Ladders or similar tools can indicate that an individual attempted to access the property from a height, often a tactic used in illegal entries.

In contrast, secure windows—those that are intact and properly closed—suggest that an intruder did not successfully enter the premises, making them an unreliable sign of illegal activity. This reinforces the understanding of security measures and intrusion detection in law enforcement training.
