Seems I'll need to explain the players thinking here.
I think the slavery case for the Amarrians is pretty straight forward. Yes they do it. Anybody who succeeds in bringing large amounts of lower generation slaves to the market will make mint. -Not only in isk, but power.
However currently the powers that be frown on this. It is even politically wise for them to see that those with the 'lean and hungry' look be forced to take risks far beyond the normal scope of Holders, clergy and merchants.
Getting caught is same as being unworthy in some measure (Intelligence, power or just luck). So anybody who gets caught will be treated as a rogue, likely to full measure of the law. (Unless they can circumvent it.)
Despite that, this level five mission brief reads as a prejudiced one. Taking what our mission agents say as truth -and nothing but- OOC or IC is going to lead to trouble. OOC headaches and IC insanely different views of the world depending on where you do missions. Though IC that's ok isn't it and actually something to support.
It does tell how some of the Gallante are likely to see and react to any Amarrian operation within Gallante space. It also tells us that at least some Amarrians are investing in foreign corporations. (Or flat out buyin such.) Cause if that corporation was clearly Amarrian, they would not have gotten the job in the first place.
So. There are plenty of Amarrian people of different classes who have turned to 'illegal slave taking' in order to gain money and power back in Amarr. And that there are plenty of racist Gallanteans who will assume worst of any Amarrian. What else is new?
What I am trying to point out here is that the mission brief itself is written in such a way as to bring up, both the horrid reputation of Amarrians and the lack of facts on what the Amarrian owned corporation is actually doing.
