The criminal code is brutally harsh about assigning responsibility where the lower orders are concerned. The kid sitting outside in the car while the others rob a convenience store is responsible for the clerk’s death, even if he didn’t know she was killed. So is the grandmother or girl friend who harbors the suspect knowing of his crime.
Try this on Goldman Sachs, AIG, Countrywide, or BP. The jails would burst. The shakiest entrapment and encitement tactics are routinely used against suspected terrorists, but almost never against bankers or CEOs or industrial polluters. Not to report a crime is a crime for you, but not for them. Shielding a criminal makes you a criminal, but not them.
Where’s the fairness? Fairness is for suckers. Grow up.
