I read the article. The taunting sort of bothered me, BUT that's what happens when one is hung by those with families murdered by your regime. Did Hussein deserve to die with more dignity? Maybe. Maybe not. It was more than he gave out.
But do we want to stand on the level of a Saddam Hussein? We´re better, I hope. That´s what executionees in the US are treated with a rest of dignity, like allowing a last word, having a priest chat, a last meal, better clothing, no insults from the victim´s relatives, etc.
Obviously, the Shi´ite Iraq wasn´t better than Saddam. They made sure by ONE EXECUTION to offend the Kurds and Sunnis both, they used their fat chance.
