How Can One Criminal Try Another?

Some are currently worked up because the President Wade of Senegal has reneged on his promise to send ex-Chadian dictator, Hissene Habre, back to Chad to face trrial for crimes he committed during his unholy reign. What these people seem to be oblivious of is that the current president of Chad, Idriss Deby, is not only the one who overthrew Hissen Habre in a military coup, but also worked for the former dictator as commander-in-chief of the army. Deby himself cannot be innocent of the crimes Habre committed. Even more, Deby has himself become a dictator who only cares about prolonging his reign in the impoverished country. Habre should be made to answer for his crimes but it will be ironic for him to be made to do so by his own accomplice.
