The NATO forces were seeking out Colonel Muammar Gaddafi and this is a casualty from that effort.
This is the difference between the former President of Egypt, Mubarak and a radical dictator that will not reliquish power while actively killing civilians.
I remind, the 'empowerment movement' in the Middle East was started as a non-violent confrontation of government to bring about change. In Libya, the non-violent confrontation was met with not only violence in the way of police shooting people, as in Syria, it was met with the Libyan military turning on its people. As far as Colonel Gaddafi was concerned, he didn't care of anyone survived the day, except, him, his loyalists and his family (which may or may not be loyalists).
Killing vast number of people is called genocide. I don't know what else this is called. When Colonel Gaddafi was opposed it was by peaceful protest. There is no international recognition of any authority to allow a country's military to turn on civilians. To this day, the 'opposition' to the current dictator is still not well armed to even call them an army. The military infrastructure of the opposition is basically, 'Every man for himself.'
Colonel Gaddafi did not leave the opposition to his dictatorship any choice, but, to take up arms against him in whatever manner they chose. The opposition Libyans didn't want this. They didn't want the violence. They were left no choice when one is staring down tanks and roof top assassins. If anyone should be screaming 'assassination' it should be NATO for the innocent people of Libya.
NATO is doing their best to find the killers and stop them. This isn't simple and as everyone can attest, the problem of discerning civilians from combatants causes deaths of people unintended. NATO is saving lives. That is a fact.
