So, Gaddafi is dead, apparently lynched after being captured in Sirte. This is traditionally what happens to dictators - witness the brutal death and post-mortem hanging of Mussolini. But that doesn't make it right. Criminals, even those who have committed crimes on a vast scale like Gaddafi, should be given a fair trial, and if convicted, imprisoned. Summary execution, show trials, and state-sanctioned murders are the tools of tyrants, not of a democratic society based on justice.
