IANAL but the U.S. has a court system that can enforce criminal negligence. If Walmart starts selling exploding landmine toys, they can be sued for putting people in danger. Additionally, parents should do the due diligence of investigating the safety of toys before buying them. Do we really need a giant bureaucracy funded by tax payers to literally go through every product sold in the U.S. and go through a rigorous safety inspection? Do you have any idea how much that would cost? Why not just let private safety rating agencies do the job? Or how about buy only American toys made locally? Finally, there's always going to be ignorant parents that don't do their homework. What ever happened to the idea that having kids is a RESPONSIBILITY. Well, be responsible and don't buy cheap Chinese toys from Walmart.
