The German government apparently intends to prosecute pirates recently taken in custody by the Dutch frigate Tromp, after Dutch Marines fast-roped down from her helicopter to retake the ship.
Actually prosecuting pirates has been rare. In most cases they are released after apprehension. The problem has been finding a venue for the trials, compounded by the difficulty of getting witness to the trial site to testify. Kenya had agreed to provide a venue, but they have a backlog, and are now refusing to accept any more cases. There is currently a resolution before the UN, presented by the Russians, asking the UN to review the situation and make recommendations so that there will actually be some consequences to the crime, beside a good meal and medical treatment before being freed to try again.
