It’s hard to do consistently, but I try to think about major media outlets as the dial on a gas stove. If they turn the knobs on a story, the flame gets bigger, even to the point of being too volatile and out of control. Russiagate is a good example of this.
If the outlets turn the gas down though, the flame can barely survive or even die for a given story. Examples here abound, even in the last couple years alone: Hunter Biden’s laptop, the Butler, PA Trump assassin, etc.
All I know about the Luigi Mangione and NJ drone stories are that the gas is being left on for both stories.
