How far does this logic apply? If it covers building machines used to kill without justification (I'm assuming you wouldn't point this out if you thought the machines killed justified targets), does it apply to someone running a website teaching people how to use malware? Someone using malware? Someone running a website dealing in harmful material that is mostly illegal? Does it matter if we say the person lives in a place where the local authority allows for this activity?
