DUI and drug laws are state issues. Most States will bar all felons. But the domestic violence issue is a federal law. Before the early 80s it was very common for people to plead guilty to ordinance violations that are covered by the assorted domestic violence acts.

This created a few problems for law enforcement officers, soldiers, security persons, prison guards, hunters, etc.

Bubba pg to a glorified traffic ticket in the 70's, goes out to shoot a buck, and winds up in federal prison.
