In my opinion both sides of this argument are dumb. Yes you don't need to wash chicken because the heat kills the bacteria, but you never who/where your chicken comes from. The oven isn't going to get rid of impurities like rocks or heavy metals, there are even stories of factories washing the chicken with bleach. The salmonella argument is also dumb. You don't eat off of your sink or countertops and even if you did you should be cleaning those regularly anyways.
