The reason for why it's recommended becomes apparent when the four guards stop moving and take what is probably a protective stance. The speculative wording is because they aren't faster than Lapine's shooting arm and the bullets get through. Not all of them, but enough to show that the King probably knew what he was talking about when he said that only an impossible weapon was going to do him in.<br/><br/>And while none of the other's attacks get through the defensive formation, it does keep them from moving any closer to the motel, which is probably good considering that one of the guards' armor is quickly losing its gold trim.
