Stellar Regional Patrol and Peace Enforcement is a confederated union of conscripted able bodied men and women whose ideals and commitments are of the highest order; dedicated to the concept that rule of law should extend beyond the reaches of civilization, the Corporate COmmonwealth, and into the out reaches of known space.
Working from a networked set of regionally positioned central bases squads are assembled from the best of local law enforcement and armed forces of kingdoms, colonies, and nation-states in a concerted effort to rein in the criminal element that would otherwise ravage the outer rim and unaffiliated worlds outside of the Commonwealth. The goal is to insure the safety of commerce and travel for citizens of the Commonwealth outside its territories and strengthen the rule of law for those who would see a better world for it.
Or, at least, that's the line served at the recruiting stations.
Asking anyone who happens to live, work, and travel in areas under the Stellar Regional Patrol and Peace Enforcement - most commonly known as just "Patrol" - and they will paint you a picture of what is essentially an armed band of thugs with badges; violent, often misplaced war veterans and cast offs from worlds that could find no better a thing to do by them but to give them a badge and set them lose into space where they could do little harm to anyone of any great significance.
And there may be some good truth in this idea. One only needs to review such cases as the Drabmen Importers affair to see evidence of this. When Patrol originally stopped an inbound freighter under Drabmen contract it was claimed for improper registration of goods. Though, after the bodies had been removed, and the cargo cataloged, was it discovered that this was not the case at all; all papers were in order. The surviving members of the Drabmen guild... both of them... also sited in their depostion that a number of items were missing that had been accounted for at launch.
Though a complaint was launched, no charges were filed, and the officers involved were cleared of any wrong doing or use of excessive force by a department investigation. During a follow up investigation, the remaining two members of the Drubman guild could not be located despite evidence they had begun to rebuild their importing business. With no surviving witnesses the case was eventually closed.
There is also a second theory that Patrol is actually funded by The Corporate Commonwealth as a way to subvert territorial treaties and set up the ground work for a structured take over of commercial interests, to cement a world's induction. While Patrol has had joint operations with Commonwealth forces, these have been with complete transparency and following all protocols and treaty obligations. Officially the Commonwealth is all too happy to help spread the security and stability of the rule of law to the outer worlds not yet in its jurisdiction.
The rights to regulation and stability are happily shared and fostered by The Corporate Commonwealth who gladly share them with all eager life in the galaxy.
