“Make the enemy live up to its own book of rules.”  Now in play in the comments at Andrew Gelman’s website where he discusses proposed EPA rules on open data.  Some commenters are upset.  “It also puts many of us in the position of arguing against open data policies in order to support better policy-making. As I said, it is unfortunate that this issue has been set up this way. I’d prefer to support open data AND support EPA research based on the best data they have available, even if it cannot be publicly released.” [my emphasis]
