Re: David B. Cruz
Professor David Cruz was recently interviewed about a controversial bill that was passed in Connecticut. "Paying even modest attention to the bill’s definitions should make it clear beyond doubt that it will not be the source of protections based upon the age of people to whom one is attracted or with whom one has sex," Cruz said.
