You will never know the answer to your question.My belief is that it may have been very possible to draw on one of those doe's if done very slowly.Deer will accept very slow movement if they don't know what something is.The challenge would have been at the shot,If the target doe looked away and you got your shot off probably a dead deer.If looking at you or has got you in her peripheral vision,there would be a good chance of a string jump or a drop and spin on her part.Resulting in a hit other then the one you intended or a miss.
