Now, I have a theory. This “ninja” wasn’t actually trying to steal anything, I think he was just some lonely loser on a “mission”. He probably saw that “cut the phone line” thing in a movie. I bet he used a bowline knot to tie the guy up after he learned it in scouts. I have a hunch I’m right about this. I can just picture him sitting at home in his mom’s basement, kicking himself for leaving fingerprints.
That’s not the ninja way.
