Even though I posted what I did earlier about a deer living after a shot passing thru its body cavity, I finally had time to look at a lot more of the pics here, and from some angles its hard to tell, but if I were a Referee on sundays..."after further review, the ruling on the field stands, the arrow passed over the deer's spine".

Like I said some angles make it look bad, but the clearest ones I think show it over.
