I am the Kat that Walks By Itself

I thought, if there was someone dodgy in charge, they might have died in the Downing Street massacre (which was just after Tosh joined Torchwood), and someone from the good old days (eg Benton - no, maybe Bambera is more plausible) might have been brought in to clean it up.

Talking of Bambera, UNIT seemed to be doing fine in Battlefield; I thought we were given a date for that story, but the synopses I've found online just say "the near future" or "several years in Ace's future". It was broadcast in 1989, which suggests the events took place in the 1990s. So Something Happened around the turn of the century while the Doctor was distracted, and the good guys like Bambera were sent off somewhere else?
