I agree with +Danielle Barnham
. I've been doing archery (recurve and compound bows) for the past two years and there's no way accidents are going to happen other than pointing at other people with a drawn bow. Unlike a gun, you can't shoot yourself! However, just like a gun, you NEVER point a bow at someone, even if there is no arrow nocked because the other person may not see if there is an arrow or not (it's a small point :P).
The only time I've hurt myself at the range was that the bow string dug into my fingers too deeply when I drawn (I have a 45 lb pull strength recurve bow).
The only thing that may get hurt is your bow -- NEVER pull and release a bow string with no arrow nocked! All that kinetic energy has to go somewhere and it'll go into your bow, which could severely damage it!
