I see no point in keeping the situation a secretly, mostly because the detectives and forensic experts will get to the offender sooner or later. All the time in between is just living life in guilt, fear, and shame.
(Bolded mine) This I can confirm; the Toronto Sun featured on its front page a few days ago the Cold Case Squad that had just solved a 17 year old murder case, and went on to document many other long unsolved cases that were eventually cracked.
May as well have your friend go to jail early, so they can come out early, and hopefully, still live a decent life.
This, however, may not be the case in every country. Only in some countries are the rights of both victim
and offender protected.
This does depend on how the offender plans to do afterwards the accident happened, even though the wrongdoer is to be rounded up by policemen sooner or later. If they wish to have a more discreet life following a long sentence in jail or only seek for a slight moment of repose being himself buried in complete oblivion of infernal lot.
Yellowbird23 - This is what I understand from what you are saying: Though there exists the eventual possibility of being caught, it is better, till then, to enjoy that momentary and public freedom, oblivious to the impending hell - rather than - going to prison, serving a horrible sentence, and being freed to return to a life of disgrace.
This may hold logic if we're not applying the present legal and ethical world-view - which is governed by physical laws (a.k.a. the five-sensory world.)
You may be looking at it from . . say, Gary Zukav's 'non-judgemental' viewpoint - whereby the victim's death was only a detail in a grand plan that involved non-physical reality - or you are following the philosophies of the Buddha or Helen Schucman, and going with 'the flow'. as is, till 'karma' or destiny, or 'luck' has its way with you (as it did with the victim.)
It doesn't nullify the answer to the question at the core of the professor's query;
would you volunteer to confess to the crime - or remain an accessory to the fact? It does state a philosophical (or fatalistic) reason as to why you would remain an assistant to the criminal.
