we're facing if this moves sideways

[Mike Hussey]

In a room, Col Eric Byer and his team presented with a box full of files. Zev Vendel drawn to Bourne's files:

Eric Byer: And Bourne... I don't care if they bag him and drop the body on the sidewalk. We're not going to touch it. You're going to turn off that side of your head now and get with the rest of us here. And you're going to start to consider the magnitude of what we're facing if this moves sideways on us.

What does "this" refer to?

I'm pretty sure it refers to something they've been discussing previously. What that is I can't say. I'd have to see what came before.

If this problem moves sideways, we're in trouble.

It the situation gets out of hand, it wll become a serious problem.
