The sirens are on the coast, no one “uphill” would have heard them. Those nearer the coast where the sirens would have been heard have been TRAINED for Tsunamis...not wildfires. The sirens for those who could have heard them would have told the people to head for higher ground (into the fire) or up into buildings, where they would have been incinerated. They need warning sirens for the whole area, and a different SOUND for Tsunamis and Wildfires ... (Same Sirens, different sounds). The press needs a scapegoat, and they are focusing on this man. The sirens not going off was NOT the problem, and the man’s decision NOT to sound the sirens probably saved lives. Tough decision, he’s a hero and only someone familiar with the (Faulty!) system would have understood what to do, which he did.
I agree, the sirens would of confused people and possibly led to more deaths. This fire was a one in a million event: the fire, the unkempt dry vegetation, and winds caused by the hurricane passing nearby created an inferno that moved quicker than anyone could predict. The only thing that can be done is to learn from this: have plans to maintain vegetation to lessen the chance of wildfires, develop a warning system that can be used for different types of events.
