An Expert

An expert makes mistakes in his narrow field of expertise

Not an adept listener, but a keen interrogator

An expert is planted to achieve the mandated objectives

Most sought-after are the retired radicals

Experts wear expensive suit, and use beautiful language and jargon

Two observations:

One, if Columbus had waited for the approval of an expert committee

He would still be at the docks

Two, editors are full time experts

Appointed to kill the initiatives of aspiring writers
