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 meets on Fridays. This week, they met on Thursday. This indicated to CNN that there would likely be unusual activities related to an indictment.

So they chose the homes of the people most likely to be on Mueller's list, including Roger Stone.

This is what is called "journalism". It takes time, money and thinking. Maybe Fox News should start practicing journalism if they would like to get this type of scoops.
