Re: PBS
Under your scenario, that would lead to an "untrue" conclusion, which if accurate, would constitute "bias". If the conclusion is accurate, it cannot be biased
As reported by the former CIA officials, and what we know over time, intelligence was indeed "cherry picked" to produce apparently desired results.
BTW, being ex-CIA certainly does not or should not, diminish their credibility. If they disagree with policy, or the use of the intelligence they devolped, the only honorable option they have is to resign. They are not free to openly criticize leadership and remain under the employ of the Gov't Same is true for the military leadership, which is why one general did resign, and only retired generals have criticized policy.
