When people talk about "criminalizing policy differences", there's a crucial, question-begging assumption, namely: that no one actually broke the law. If that's right, and if we know that it is, then of course investigating previous administrations for law-breaking is just a "vendetta". But whether or not laws were broken is precisely the point at issue.
If laws were broken, then the fact that they were broken as the result of "a deliberate, and internally well-debated, policy decision, made in the proper places" is no excuse -- if anything, it makes investigation and prosecution all the more important. And it also means that the people who favor prosecution are not the ones who "criminalize politics".
That honor goes to the people who broke the laws while holding public office. If we care about the rule of law, and about the idea that ours is a country of laws, not of men, then we should investigate those who break the laws, especially when they hold high office. The Presidency is a public trust, not a license for criminality. |ObWi|
