If they scuffled over the taser, then the taser will have Scott's prints on it. He had the prongs sticking out of his leg. Dropping the taser next to Scott's body isn't evidence of a lie because the taser itself contained evidence. If the Officer was going to lie, he would have placed the taser in Scott's hand.

Respectfully disagreeing on conclusion - if Slager & Scott scuffled over it, taser would [definitely] have Scott's prints on it.
Maybe. Maybe not.
Sometimes forensic techs cannot match fingerprint data on an item (like Taser) to a person's fingerprints.
Sometimes smudged, incomplete, over-printed by others' prints, etc.
I follow the line of thinking - if LEO was 'planting' evd, he w/h/put taser in Scott's hand or verrry close by. Seems logical.
Scott's DNA on Taser? Seems logical. Maybe.
