Well by that logic they would obviously lay mines themselves, and certainly wouldn't leave tracks all over the place 2 weeks prior to the explosions.

Those tracks are obviously just drifting or perhaps looking for something. I don't think the Russians mislaid their own pipeline. Maybe communications lines? Or smuggling? Looking for lost treasure?

In any case the point stands, it just makes no sense for the Russians to do this, and contrary to what is claimed, this presentation does not offer any support of that theory IMHO.
