GREEN BAY, Wis. --The company that sold weapons to the Virginia Tech killer and ammunition to the NIU gunman announced a new initiative Wednesday.The president of the Green Bay-based Web site gun dealership said he believes his link to the crimes is random. But he thinks he has a special responsibility to do all he can to prevent further loss of life. "That's why I started a Web site called gundebate.com. Gundebate.com is meant to help spur a dialogue on the best ways we can stop mass shootings and to be a clearinghouse for public safety ideas," said Eric Thompson, TGSCOM, Inc. President. Thompson is also fighting for the right to carry concealed weapons on college campuses.
