Alan Meese on Targeted Killing
Alan Meese: On the Legality of Congressionally-Authorized Drone Strikes. Earlier thoughts on this subject from Professor Meese: Should the United States Replace the Seal Teams with Grand Juries?
I'll take this opportunity to make a quick general plug for Professor Meese's somewhat obscurely-named "Bishop Madison" blog ("occasional commentary on political economy, law, et cetera"). He has some outstanding posts on originalism -- a couple of his classics are: On the Appropriate Scope of Judicial Review and Original Meaning or Something Else (and if so, what?).
Note: Professor Meese is my former co-clerk and a good friend. I think he's wrong about drone strikes, though, at least with regard to American citizens who aren't actually engaged in combat. I'll post my thoughts on that point shortly.
