Easy, just because we don't have a sight bolted to the bow doesn't mean we don't sight the bow.How do you stay 'sighted' when you do not have a sight???????????
However, longbows at short distance could be a problem, were would the arrow go if loosed while pointing at a 20 yard target, way, way over the top.
Umm, there may well be some merit in the current wording.
