A good discussion, including
here, over at
Balkanization on executive power, especially when it is used recklessly ... but at times constitutionally (see, e.g., Marty L. on the troubles of ignoring institutional norms, such as the whole prosecutoral purge mess). Secrecy, bad characters, and so forth clearly leads to some crossing into illegality, but overall, the whole debate underlines the value of sound government. The idea, coming from some quarters, that the reverse can be defended on bare legality grounds (and at times not that well), notwithstanding.
