weird dnr law

 I am just curious if this bothers anyone else. The dnr has a law stating that it is illegal to use any "cocking" device to hold back your "bowstring"  on archery equimpent. In my mind, this would make crossbows illegal. I am not against crossbows i guess(for people who can't shoot a real bow) but it seems un fair to me that a guy who wants to use a compound  but has an injury isn't allowed to use a draw loc type device but yet he/she is forced to get a crossbow if they still want to "bow" hunt .
