Targeting Illegal Gun Buys In Baltimore In Baltimore last week, ATF, NSSF and Maryland's U.S. Attorney launched a major campaign aimed at deterring illegal gun purchases in the city. The "Don't Lie for the Other Guy" campaign is designed to educate firearm retailers on how to 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. The city's kickoff was featured in the Baltimore Sun, Baltimore Examiner and on local television.
