Crucial to society. It's in the best interest of the accused that other people implement steps 6 and 7. And so realistically they ought to be implementing them too.
My point is that we shouldn't just be looking out for our interests. We should be working co-operatively to look out for everybody's interests. Ultimately this benefits ourselves too, but that's not why we should do it.
I think the current system is broken. We should be trying to align our incentives. Urging people to act against their own self-interests is self-defeating.
