not quite, Hal, Dorin is whithin the Fakir sector - entirely controled by the Empire (bar the Dorin system itself).
The arrests took place several weeks ago, by Mr Powers working under the GE. At the time, Dorin was controlled by a non-government faction, which then handed over planetary control to the Trade Federation in order to prevent any further arrests.
Several Builders and abandoned players where caught before this happened though, and those are the ones you can see arrested currently, Tahil.
your perfectly safe under the current administration of the planet, no matter which faction you decide to join, or your race.
