 FACT: The rifle they say was used to shoot officer Delko was a Ruger  10/22, yet the bullet they say he was shot with was a .223 caliber.  The 10/22 fires standard rimfire .22 cal. bullet, thus the model  designation. If he were shot at close range with a .223 cal. bullet,  there would be precious little left of his neck and he most likely  would have been dead before he hit the ground.
