Webb said early on that he was in contact with former and current FBI, whitehats presumably. He must be a target for sure, and could be taken out as he knows. He could also be protected by whitehats. There is no evidence to suggest that he has been anything but truthful. He is a gifted researcher and has been looking at these thing for many years.

I'm sure the real shills don't attack Webb so much because they don't want any more attention than necessary on what he's explaining. They fear his videos going viral.
