Death toll of northern California's Mckinney Fire reaches 4

Firefighters, already in short supply due to labor shortages, are exhausted. And with these erratic fires burning so hot they create their own weather, the conditions often just aren't safe for crews to even try to slow down the flames. Retired firefighter Timothy Ingalsbee runs the Oregon-based Firefighters United for Safety, Ethics and Ecology. It's a group pushing for an overhaul in U.S. fire suppression and prevention policies.

Ingalsbee says mostly crews can just try to protect homes and lives in the fire's path - you're not going to stop these blazes. That's, again, the plan today on the McKinney Fire in Northern California, where firefighters are working to slow its eastward spread toward the town of Yreka.
