the cardassians have got the Obsidian Order.
the Romulans have got the Tal Shiar.
The Federation has got Section 31.

but what do the Vulcans, Klingons and the Bajorians have?

(PS: i dont know the answer, but its something that always bugged me!)

I don't think the names of the similar Klingon and Bajoran agencies have ever been given. The Vulcan one, maybe, but I can't remember at the moment.

Well, the Vulcans are part of the Federation. But back in Archer's day, they had something similar (see: "The Andorian Incident").

It's non-canon, but I believe the Klingons have the IIS (Imperial Intelligence Service).

In "Gambit II" the Vulcan's had a security agency named the V'Shar, and Riker/Picard didn't seem surprised to find a V'Shar agent working undercover, so it must have some intelligence function as well.

Anonymous: but what do the Vulcans, Klingons and the Bajorians have?
Luigi Novi: Each other.

Seriously, the Bajorans only came out of a 60-year Occupation at the beginning of the series. They didn't exactly have the time or the need to have a dark and sinister security agency since they had the Federation's protection.

Actually, they did not trust the Federation that much during the first few seasons, and we did see the beginnings of a "sinister black ops" organization, the Circle. Fortunately, it was exposed before it could become entrenched. (Or was it? Mwa-ha-ha)

Tom, the Circle was a militant isolationist group that sought power, not an intelligence agency or "black ops" organization.

Not yet, but as they had made inroads into both the provisional government and the spiritual leadership, if they had become entrenched they would have become one. (I did say they were the beginnings of a ... .

No, they would've become the new government. An intelligence agency is simply a smaller organization that exists under the government's purview.

The closest I suppose the Bajorans "may" have had to a black ops organisation is the remnants of the Kohn Ma. But it would seem unlikely that any Bajoran government would ever officially sanction them and the Kohn Ma seemed answerable to no one.

Again, the Kohn Ma was an extreme nativist terrorist organization, not a black ops intelligence/security organization, or even anything that resembled one.

Security/intelligence organizations are characterized by professionals who are highly trained, funded and skilled, have sophisticated resources, conduct investigations, take action against certain people and other elements when they have a sufficient modicum of evidence, maintain professional relationships and contacts with other such organizations, and/or keep detailed and organized information databases and records, which is how they are often held accountable for their misdeeds. Most importantly, such organizations are (at least in theory) part of the legitimate government and chain of command therein, whose mandates are to carry out legitimate actions ordered by their government, which is why they (and their government) can held accountable for their actions.

None of this applies to terrorists, who, even when they are funded and trained like Al Quaeda, are essentially poor, ragtag civilians who operate in a rogue manner from any government, without any legal mandate, often for the purpose of simply exacting revenge and demoralizing a people, who improvise with crude, unsophisticated methods, and who do not concede accountability to anyone. (Mind you, I am not attempting to promote or excuse the misdeeds of the former over the latter.)

To say that the comparison between organizations like Section 31, the Tal Shiar and the Obsidian Order to the Kohn Ma or the Circle is inaccurate would be a gross understatement. The two types of groups are simply not analagous.

It seems to me that the only commonality between them on which some may make this comparison is that they both take hostile action against their perceived enemies, which is such a generalized concept that it could be used to describe schoolkids participating in a lunchtime brawl, and would expanding the definitions of the two types being compared here to the point of making those definitions meaningless.

Wish I could help

Erm...didn't you START this thread?

Luigi youve knocked me down a peg or two again I feel about two foot eight now!! I'll end up shrinking into nothingness at this rate!

Sorry, Admiral. And since you're an Admiral, I guess that'll be 30 days in the brig for me.

Methinks the walls of the brig will soon be covered in funny red headings...
