I am an avid bow hunter and i would never do such a thing. First of all if he wants to kill some squirrels he could just use his bow, just take some small game broadheads along. Second if he is planning on hunting that spot often he will not have much luck. Deer in that area will avoid that part of the woods all together if he does that often. They may even be so stressed that they up and leave that area all together. I would say that it is a bad idea for sure!
