Wildfires aren't like other natural disasters. You can't trace a hurricane to the first gust of wind, but you actually can trace your way back to a wildfire's first spark. And sometimes, someone has to pay.
In 2007, the Witch Creek Fire caused billions of dollars worth of damage in Southern California. While the fire was still burning, wildfire investigators showed up on the scene, and traced the flames back to where they began. The results spawned a ten year legal battle over who should pay for the damage.
