as i understand it, cases on federal property usually go to federal court; however, the feds can choose not to prosecute and refer it to state court as anything that happens within the borders of a state given rise to jurisdiction and venue UNLESS there's a specific federal statute granting exclusive and sole jurisdiction to the feds. for example, there are times where MP/JAG will decline a case where the crime occurred on Fort Cavazos/Hood...usually a very minor deal they don't wanna fuck with...and call Bell Co. S.O. to handle it (they, too, can deny prosecution for their own reasons). admittedly i'm not at all well-versed on the rules or law here, simply stating what happens in the real world. i could very well be wrong and what i just stated may well be some sort of local practice where everyone turns their head. but we've tried to get cases kicked arguing exclusive federal jurisdiction and denied relief each time.
fucking county court at law judges, man...
