Several things actually. How do you know that the arrow has entered the body of the deer? If you look close, you'll see the metal insert in the shaft of the arrow. Secondly, if the arrow had entered the deer's body, there would have been at least some blood. Also, there would be a bit of a hump where the arrow entered under the skin. There is none. There is no blood. So look again there, Skippy - your eyes may be failing you.

But, this pic is a fake anyway so it makes little difference to debate over whether it is a filed point or not. Take a look at the arrow - see any brain matter or muscle tissue or skull fragments? When's the last time you shot an arrow that was nearly 4' long?
