How did CNN know that there would be a raid on Roger Stone's house? They even filmed the FBI raid !!?

Normally, the grand jury will meet on Friday. This week they met on Thursday. This indicated to CNN that there would likely be unusual activity in connection with an indictment.

So they put away the houses of the people most likely on Mueller's list, and Roger Stone was one of them.

It's called "journalism." It takes thought, time and money. Maybe Fox News should practice journalism if they want to get those shovels.
