I doubt LaCanfora completely makes things up out of thin air but I would bet his sources are the bottom dwellers in the organization, like maybe the janitor heard somebody yelling something and LaCanfora runs with it embellishing, stretching the truth or reporting things out of context.
And Barry likely has legit high up sources but they're going to feed him the info that paints the organization in the best possible light.
So you have to decide for yourself what the truth is but I would just say try to take all information from "unknown sources" regardless of who's reporting it with a huge grain of salt.
