What can create a timed opportunity for fire setting?

The presence of civil unrest can create a timed opportunity for fire setting because during such chaotic events, law enforcement and emergency services may be overwhelmed or distracted. Individuals looking to start a fire may find an opportunity in the confusion, as the focus of authorities shifts to managing the unrest rather than monitoring potential fire hazards. Additionally, during civil unrest, there may be less vigilance from the public and businesses, making it easier for fire setters to act without immediate detection.

In contrast, other options like the availability of fire departments or the presence of fire extinguishers suggest measures in place to prevent or quickly respond to fire incidents, thereby reducing the opportunity for fire setting. High visibility conditions can sometimes deter such actions as they increase the likelihood of being seen, thus discouraging fire setters rather than facilitating their actions.
