He was caught during battle. When you catch someone during war, you can either kill him or take him as a prisoner. The ones fighting against him are not 100% perfect muslims. We don't even know who they are, why they are fighting against Qazzafi. Who knows? What's the point in preaching them on SF about what to do to prisoners? Is any libyan rebel reading SF here? They were raged and they had anger against him. They killed him during battle, after fighting for so long.. No need to give fatwas against them and portray them as bad. Just give them the benefit of a doubt.
