What is value of FIR or Complaint which is drafted by well experienced criminal lawyer?

There are thousands of cases where after incident of crime, complainant side consults a criminal lawyer first and then files FIR drafted by a lawyer. ( Mostly to add more relatives of accused).

Once in a case such fact was admitted by complainant and yet judges did not throw away FIR on ground that it is concocted by a lawyer.

There are two views.

1) According to one view, People do not know law and it is okay if they get draft their FIR by a lawyer and

2) Another view is such that such concocted FIR, prepared under guidance of lawyer, is devoid of truth and ought to be looked with suspicion.

I hope that some authoritative pronouncement should come on this issue defining value of such FIR.
