"This morning I read that the group of hackers collectively known as ‘Anonymous' targeted web sites associated with Koch Industries. The story is in many ways a perfect example of the dangers of the type of excessive disclosure so-called campaign finance ‘reformers' are demanding, and why it's so important to protect citizens' right to privately associate and speak out in politics and on public policy issues.
