Heh! When a pol or Party relies on interest group politics, sometimes those interest groups conflict with each other, and sometimes those interest groups come into conflict with principles (e.g. "innocent until proven guilty") or reality. The Chill can recognize a railroad job when she sees it, knows railroading often fails and/or backfires, and knows the case against Officer Wilson is flawed and less than weak. But to state those things would be to run afoul of the Ds' favorite-son race-baiters.
The Chill lacks the courage to speak truth to the race-baiters' power, and lacks the intelligence to have anticipated and prepared for an utterly predictable question.
