Far better, I would have thought, to give him half a chance of coming up trumps by making technical information available if he needs it. Surely there's less chance of him causing any harm that way?:(
Still half a chance then that he (and she if we're going to absolutely correct) won't 'come up trumps' and potentially cause harm then?
Morals and ethics may or may not differ in the 'Third World" from us here in the "West" but it is therefore down to ones own individual morals and ethics how they disseminate information. I would certainly not advocate the distribution of service manuals to unknown third parties on both moral and legal grounds.
