Public fire safety

My neighbors have certainly failed that test. Today they decided to light up a fire in their small back yard to burn some of the planks used while working on the house- Their house is surrounded by my building, neighboring houses and whole lot of trees and bushes and wooden fences. I'm on the second floor and the fire went above my eye level... not to mention a 4-5 year old kid sitting on a swing set nearby.... absolutely crazy!
