I am pretty sure they did at least pretty thoroughs scan and trap-check for everything they could find- the show didn't start on literal day one. Also, there were people there for the whole changeover, Bajorans and Odo, while the Cardassians left really fast, so not a lot of time to lay subtle stuff (and the most subtle deeply buried trap was indeed laid long ago, the anti-riot on) and probably not wanting to provoke an incident by leaving things too bad.atg wrote: At the end of the day:
- The Federation took over a station without having full control over it's internal systems. From an enemy specifically known to love to leave booby traps behind (mentioned both by Kira in the pilot and by O'Brien in the episode where they go to the other abandoned Cardassian station).
They didn't have complete control, but nor did they likely go in blind.
Heck, the Federation may also have had some interest in having a whole station of Cardassian tech to get familiar with. Sure, it's not as good, but they're a curious bunch and expanding knowledge of a rival's systems is a useful thing. It does mean going into the next conflict with Cardassia (which did come), they have much more hands on knowledge. Which makes it much harder to catch them offguard if they, say, need to capture a *hostile* Cardassian station in the future. They now know the anti-riot protocols, what normal operation looks for, and every hack and back door that O'Brien figures out over years of working there- which is, presumably, a lot.
So they may have been learning from the incidents in question, but learning a rather different lesson than you read into it ("Neat, we now know how Cardassian anti-riot program traps are buried!").
They've got a bit of the 'stick a fork in the energy cloud' mentality.
Also they likely did not reckon on how absurdly well-armed the Federation could make a mining station.Tribble wrote:atg makes a good point about the civilians; after the virus incident all non-essential personnel should have been evacuated until they knew with absolutely certainly that there weren't other hidden "gems" in the computer programming or other booby-traps.
As for replacing the station that was a non-starter; the Bajorans certainly wouldn't have approved and neither would the Cardassians. IMO the Cardassians initially tolerated the Feds presence since technically it was a civilian station under Bajoran control with the Feds merely providing oversight; I doubt they would have put up with an official Federation starbase and military presence (though things changed when the Dominion were discovered).
