Why does Wilson differentiate between being the original source and being the second or third guy in.
What's the difference?
Really? You can’t see the difference between being the source and commenting “when asked”?
Huge difference. No one wants to be identified as the original source for reasons of reputation. It gives a person an aura of being untrustworthy ... a potential client will think "if I give him my business, what confidential pieces of info will he leak?"
Responding when a reporter who has a tip comes to you is just perceived differently.
