I had 1200-1500 calls a year so we had to be smart. I had an arsonist who hit other areas, they'd set a small fire in a dumpster on one side of town to draw the engine away from where he was going to strike. The first dumpster fire came in in my area and the local Captain responded with a brush truck and 5 minutes later came the structure fire call. The first due engine got there in 2 minutes and knocked down the fire. Enough evidence was recovered to make an arrest and go to trial successfully.
