In fact I find it a really bad example. Yes I think your personal AI could be allowed to tell you how to cover up a murder. I'm not entirely sure about it but seems possible.
What about your personal, local AI guiding you to modifying a flu virus for maximum contagiousness and deadliness? "Sure George, here's your shopping list. It's $1500 total in equipment, do you want me to proceed with the orders?"
Why not? There are perfectly pro-social reasons a person might ask such a question. And a bio-terrorist would have many other avenues to answer these questions.
The concept of a bioweapon attack is commonly cited but in fact there are many other defenses against actually developing and deploying such a weapon. It's commonly portrayed as easily achievable but is in fact very, very far from it. Moteover, although there is no evidence that AI makes it easier in any way, somehow this is constantly invoked as an example of a thought crime that must be forestalled at all costs.
In the AI era people seem to want to redefine the criminal act from "doing the thing" to "asking or investigating how to do the thing". Not a mindset I share.
