Few fires will burn city blocks, even in urban cities. you put the tower up, surround and drown, and the city block is saved. usually the loss is just a house, maybe an exposure if the delay is that great. but it isn't a city block unless there are other factors at play.
Yes...because they have a fire truck to do that. I'm not talking about "oh god, if we brownout an engine company everyone will die". I was talking about not actually having a fire department. Like, at all.
Besides, this is a minor point to the discussion. I'm not advocating cutting EMS funding to fund new fire apparatus, I'm not suggesting that the fire department is somehow better then EMS or "saves more lives". I'm using the fire department as an example of a service that produces, for the most part, easily noticable results. When the fire engine shows up and puts out a fire, it's easy to say "This is what the firefighters did and why it's good that they did that." I can compare two departments and say that one puts out fires faster and more safely than the other. I can do the same with plumbers, electricians, and restaurants too, the example doesn't change.
Here, lets look at it this way. Pretend that you have to sell your paid ambulance service to my town. How do you convince the Big Cheeses that your paid ALS ambulance will be worth the extra tens thousands of dollars to the town compared with an unstaffed BLS volunteer ambulance which we have now.
Forget the fire department and the cops, just answer me that.
