Don't know about ammo, but or guns, yes that is exactly what the Lautenberg amendment provides.
While I didn't know about the ammunition, I just checked, and it is indeed covered by the law (18 USC 922(g)(8) It even affects police officers and military. Military! According to a Ft. Riley web site:
the Lautenberg Amendment makes it a felony for anyone convicted of a misdemeanor crime of domestic violence (e.g., assault or attempted assault on a family member) to ship, transport, possess, or receive firearms or ammunition. There is no exception for military personnel engaged in official duties. The Amendment also makes it a felony for anyone to sell or issue a firearm or ammunition to a person with such a conviction. This includes commanders and NCOs who furnish weapons or ammunition to soldiers knowing, or having reason to believe, they have qualifying convictions.
E. Command Responsibilities. Commanders requesting guidance concerning the Lautenberg Amendment should contact their Trial Counsel or the Administrative Law Division at 239-2717. DOD and Army policy requires the following to implement and enforce the Lautenberg Amendment:
1. Notify soldiers that it is unlawful to possess firearms and ammunition if they have qualifying domestic violence convictions;
2. Check local unit files to determine whether soldiers have qualifying convictions and report soldiers known to have such convictions through command channels to HQDA;
3. Detail soldiers having or believed to have qualifying convictions to duties not requiring the bearing of weapons or ammunition;
4. Prohibit soldiers having or believed to have qualifying convictions from deployments for missions requiring possession of firearms or ammunition;
5. Prohibit soldiers having or believed to have qualifying convictions from attending military schools where instruction in weapons or ammunition is part of the curriculum;
6. Prohibit soldiers having or believed to have qualifying convictions from receiving OCONUS assignments;
7. Transfer where possible soldiers having or believed to have qualifying convictions from TOE to TDA units and organizations; and
8. Prohibit soldiers having or believed to have qualifying convictions from re-enlisting.
Did I get moved to the USSR as I slept? You must have slept a long time. The amendment was part of the FY 1997 DoD Appropriations Act (ie. "Must Pass" Legislation, which few CongressCritters read) and was effective 30 September 1996.
Passed into law while the vaunted "Contract With America" Congress was still in control of legislation at the federal level.
Unfreakinbelievable.
