Much like any other mandates it is not that simple. Sure retailers can sell used clothing and toys IF they pay to have them all tested for lead and it is cost prohibitive to do so. If they dont have them tested then they run the risk of unknowingly selling an item that exceeds the limit. That is where the fear lies.
Some people live an entire lifetime and wonder if they have ever made a difference in the world, but the Marines don't have that problem. -- Ronald Reagan
