I'm no expert but i neednt be to see the lies in defence's line of argument. If muiruri did resist arrest and tried to grab the gun, pray tell me how the gun fired through the mouth then the head. I'd expect that when i try to grab a gun, which i believe was in its holster, it'd fire downwards or get either of the two in the lower part of the body, eg legs, etc. Bt mouth, head? No way, it was a gun at work. As for their being 'relaxed', i believe its got to do with fate, knowing that what come may, fighting or crying will not change your destiny. And who is this chepkonga guy? He looks rich.
