It's partly a community issue for me. I'm not going to report various neighbours who are fiddling tax, because they are neighbours or friends. I have a relationship with them, and for me, that supercedes issues of legality, barring major crime of course. Half my friends used to take drugs as if there was no tomorrow, acid mainly, what am I going to do, go to the cops? Yeah, right.
Old slogan in therapy - you can be right, or you can relate.
