This week The Washington Post ran a series of articles (link) examining Cheney's role in crafting policy in the Bush administration. The Week magazine (link) asks if Cheney has gone too far:

It was Cheney who decided that the Geneva Conventions should not apply to captured terrorists, instituted interrogation tactics that many consider torture, and insisted that the administration could monitor phone calls and e-mails without warrants.

Has Cheney gone too far? YES!
