I’ve noted before my discomfort with this rule. Here’s a particularly egregious application. A West Virginia man attempted to set fire to a tire. The fire spread, igniting a pile of railroad ties. Firefighters responded, but stopped on a bridge overpass to identify the source of the smoke. In the process, one firefighter slipped on the bridge and fell to his death.
Prosecutors are now charging the guy who set the fire with first-degree murder.
