I've suggested to several on-line fire-conspiracy believers - to walk around their own (fire-prone) neighborhood, and look at the homes and buildings, trying to spot potential fire hazards.
I did this one day in my former neighborhood, when I lived close the the San Gabriel mountains, California. I was surprised at the hazards I saw.
Uncleared brush, untrimmed trees, unused items stored against the exterior walls, stacks of firewood against walls, trash bins stored next to walls (often uncovered), visible gaps under garage doors, etc...
Unfortunately, this seemed to fall on deaf-ears, or they pushed harder on the conspiracy issues, or I was accused of "trolling".
Not all residents are home "owners". Many are lower-income renters, who tend to rely on their landlords for brush clearance, tree trimming, and roof gutter cleaning. Many low-income landlords are well-known for preforming the minimal maintenance of the units they rent, and only do-so when required by their local municipalities. My rental, would receive inspections from city officials once every couple of years, and the focus of the inspection was on the interior......primarily - working smoke alarms and exit egress. Not once did the inspector tour the exterior of the structure for fire hazards.
I don't mean to generalize these situations too much... only from my experience and what I spotted around my neighborhood.
I agree, people are way too reliant of the Fire Departments to "put out a fire" after it has begun, rather than preventing the initiation or spread of fire, in the first place.
