Alright. It sounds stupid, but is possible. I can almost guarentee (?) that. The reason is a glitch with the Cloak and Dagger. When you're invisible and in 1st person, you can see through bricks, and look at people, items, and vehicles in real time. I recently found this out, and was wondering if we could use this as an item itself. Try it, look through the knife when in first person. See through bricks. Wonderful.
