nakamoto in front of his home. this man is now joining us live, a senior writer at news week and the reporter that investigated this piece. the face behind bit down. so this was a two-month investigation that you did, right? >> it was two months of almost obsessive sifting through information. >> when you see the video outside of this man's home, it's caused quite a stir. why do you think this is nakamoto? >> obviously, it's not what i wanted to see, people mobbing this man. that was unfortunate, i think. we went through i don't know how many leads, and the process of this research isn't about proving who someone might be. for every person you say, why could it not be him.
