Well actually...
Junkers ARE foreign, its just they've been in Liberty so long most people tend to forget that they were the Gallic espionage tool for gathering intel on the rest of Sirius.
The saying "Ones trash is another's treasure" springs to mind too. Premium scrap is money leaving Liberty any way that you look at it. Also slave running targets the lower classes of society, likely Xeno families or sympathysers. I could think of more reasons but I don't really think I need to.
While the feedback has mainly centered around Junkers, I'd like to point out they aren't the only ones in danger. Anyone caught in a foreign trade vessel, or trading goods obviously across Liberty borders should be worried as well. As was previously mentioned, Xenos have very few allies and alot of factions outright hate them.
