Osiel: How Should the ICC Office of the Prosecutor Choose its Cases? The multiple meanings of Situational Gravity

Mark Osiel (T.M.C. Asser Institute) has posted How Should the ICC Office of the Prosecutor Choose its Cases? The multiple meanings of Situational Gravity. Here's the first paragraph:

The Office of the Prosecutor (OTP) has also begun preliminary investigations in Chad, Kenya, Afghanistan, Georgia, Colombia and, most recently, Gaza.
