Who is this aimed at?
Let's assume, as a starting point, that the FBI is not completely stupid.
Then they know no-one is going to do this. This blog post is not so much instructions for users as a checklist for agents investigating what has gone wrong, when it inevitably does.
I shudder to think what sort of IoT-related shenanigans are going to attract the attention of the FBI in future; but I'm sure it'll happen, if it hasn't already.
