Nothing odd about it. The ambassador was wearing a dark suit with a dark sweater under his jacket. He was also wearing a shirt. All of that material would absorb blood.
Also, he was shot in the back and fell on his back, so much of the blood would pool under his body.
At least one bullets pushed a piece of his clothing (probably his tie) through one of the wounds in his abdomen. You can see that piece of clothing sticking up above the ambassador's abdomen.
Thanks for your response.
Many are saying he was only shot once, through the heart. Others say he was shot once, in the spine. You are saying there were multiple wounds. One of the bullet pushed a piece of his clothing (probably his tie) through one of the wounds in his abdomen. So the 'claim' none of the bullets went 'through' his body would then be wrong. And where's the blood, if it did go 'through' ?
I wouldn't be questioning these things if I thought that the 'media' (here and in other countries) always told the 'truth', and if I believed that 'governments' never did anything wrong or faked 'incidents' to gain power or fool the populace into 'favoring' some 'action'.
