"The upper arms move more slowly than the lower arms and hands. But shooting at the upper arms, there's a greater chance you're going to hit the suspect's brachial artery or center mass, areas with a high probability of fatality. So where does shooting only to wound come in when even areas considered by some to ‘safe’ from fatality risk could in fact carry the same level of risk as targeting center mass? “Legs tend initially to move slower than arms and to maintain more static positions. However, areas of the lower trunk and upper thigh are rich with vascularity. A suspect who’s hit there can bleed out in seconds if one of the major arteries is severed, so again shooting just to wound may not result in just wounding."
