Having smoke detectors, water hoses, fire extinguishers at the ready I dont worry too much about a house fire. If the guy had home insurance, he should be covered.
If you are a member of CO-AR15 you should have at least one fire extinguisher even if you live in a camping trailer. Carbon Monoxide detectors are a good idea too! You are more likely to die in a fire in your home, than be shot by an intruder. Maybe we can all learn from this story.
