"The last thing he wanted was to be put on trial, to be convicted and to end his life in a prison farm in upstate New York. What he wanted was exactly what he got - to be shot in mid-jihad and get a fast track to paradise and the Americans have given him that."

Gert-Jan Knoops, a Dutch-based international law specialist, said bin Laden should have been arrested and extradited to the United States.

"The Americans say they are at war with terrorism and can take out their opponents on the battlefield," Knoops said. "But in a strictly formal sense, this argument does not stand up."

A senior Muslim cleric in New Delhi, Syed Ahmed Bukhari, said U.S. troops could have easily captured bin Laden.

"America is promoting jungle rule everywhere, whether in Afghanistan, Iraq, Pakistan or Libya. People have remained silent for long but now it has crossed all limits."
