Influence is per system - not per station. When certain threshholds are crossed then two minor factions can enter civil war and a change in station may occur if the losing faction owned a station.
Our group has evidence that killing all ships going into a station (close enough to count as in the stations jurisdiction) triggers civil war. We've adopted that approach twice, and in both situations we triggered a civil war within the day. If a civil war is what you want, outright mass murder seems to be a reasonable way to achieve it. But the faction that station seems to go to war with, that we haven't figured out how to control.
We were killing them as we came to the station (well, the outpost). Also, note that the authority that issues bounties in this situation is the outpost-controlling faction, if that's different from the system faction.
If we didn't see any ships approaching the outpost, taking a few potshots at it before darting out of range summons swarms of cops which provide additional targets. We killed a large number of ships before the civil war happened, but we only had maybe three players working at it and they still got it done in a day. It might be that the killing of authorities had more impact than the killing of traders - that much we can't say.

I don't think Civil Unrest and Civil War have anything to do with each other.
The reason The Dukes are not getting in a civil war is probably because they already are in a Boom.
I would guess that soon after the boom ends there will be a civil war.
