'Don't Lie' Targets Illegal Straw Purchases in Indiana In South Bend, Ind., last week, ATF, NSSF and the state's U.S. Attorney launched a major campaign aimed at deterring illegal gun purchases in Indiana. The local media also pitched in with coverage of the "Don't Lie for the Other Guy" campaign launch. The Don't Lie campaign is designed to educate firearm retailers on how to better detect and deter potential straw purchases and to raise public awareness that it is a serious crime to purchase a firearm for someone who cannot legally do so. Don't Lie is a joint effort of ATF, the U.S. Department of Justice's Project Safe Neighborhoods program and NSSF.
