What gets me is the lack of moral obligation on a broader scale. Say, for example, you saw an aircraft taxiing out with the control locks still in place, you couldn't say oh well, it's not for me to tell the pilot what to do. That's obvious to everyone here.
But how about a slightly lesser extreme; you operate in the GA enviroment and see a competing outfit who's aircraft has a minor defect that will result in an expensive but non fatal or harmful incident. By keeping quiet you know the result will be financial reward for you. Again it's obvious, I hope, that that wouldn't happen, but in the legal world keeping quiet means you win and get well rewarded for it too. That's their only moral obligation.
Just as well O.J. didn't give me a call.
I know I would make a useless lawyer. Just as well I'm not one!
