Re: First Contact alternate timeline
For my own part, I've never really agreed with the "FC altered the timeline theory" for purposes of storytelling. I'm not a huge fan of "Regeneration" and I'm inclined to think it was just an excuse on the part of the producers to justify potential continuity issues by having the Borg on the show. By the same token, I also disagree with the concept of having a "temporal police" as shown in eps like "Relativity." It makes no sense to me personally, and I wouldn't trust even the good guys with that level of technology.
