Sorry but there is something really appalling about what you are saying. You are basically saying "if you're going to do something you think is illegal, make sure not to leave a paper trail so it can be proved in court." You're basically advising people not to get caught rather than to not do the bad thing. What is wrong with your world view that leads you to jump to that sentiment?
Did you miss the "Best approach would be not to do it at all"?
The first sentence is basically only a variation of "don't write it in an email if you wouldn't want to read it in the news".
If the article was about a body being discovered in a murderers backyard and I had written "ideally don't bury bodies in your backyard" you would have questioned how sick and twisted I am that I didn't write "don't kill people"? The prior is inherent to the statement.
It's more like if you'd written "if you're going to be that brazen about killing someone, at least go to the effort of hiding the body, but ideally don't kill someone at all." It would be a bit questionable to have even said something like "at least try hiding the body "
