Hawaii has a robust emergency siren warning system. It sat silent during the deadly wildfires::Some Maui residents are questioning the effectiveness of the emergency warning system employed as the wildfires spread rapidly across Lahaina and other parts on Tuesday. Hawaii’s attorney general is leading a review of the emergency response.
It’s the largest in the USA, therefore it’s the largest in the world! Americans can’t point their country on a map, you think they know what Germany and Austria are?
Bashing Americans is all well and good but I’m pretty sure it’s a specific type of siren system they’re talking about and not necessarily comparable to old war/air raid sirens.
