The Center for Democracy and Technology (CDT)sent a letter to the Senate Subcommittee on Science, Technology, and Space concerning its objection S. 2537, The Dot Kids Implementation and Efficiency Act of 2002. The House had already passed a similar bill, H.R. 3833. The CDT contends that this legislation simply cannot guarantee that children would be protected from exposure to inapropriate materials via the proposed .kids.us domain. Furthermore, the creation of this domain "sets a dangerous precedent for regulation of the domain name space...and creates new concerns about free expression online."
