1. certain

   That is authentic which is true to the facts; that is genuine which is true to its own claims; as, authentic history; genuine money.

   A 'genuine' work is one written by the author whose name it bears; an 'authentic' work is one which relates truthfully the matters of which it treats. For example, the apocryphal Gospel of St. Thomas is neither 'genuine' nor 'authentic.' It is not 'genuine,' for St. Thomas did not write it; it is not 'authentic,' for its contents are mainly fables and lies.

   Trench On the Study of Words lect. vi, p. 189. [W. J. Widdleton]

   Authentic is, however, used by reputable writers as synonymous with genuine, tho usually where genuineness carries a certain authority. We speak of accepted conclusions, certain evidence, current money, genuine letters, a legitimate conclusion or legitimate authority, original manuscripts, real value, received interpretation, sure proof, a true statement, a trustworthy witness, a veritable discovery.

   Synonyms:
   accepted, accredited, authentic, authoritative, authorized, current, genuine, legitimate, original, real, received, reliable, sure, true, trustworthy, veritable

   Antonyms:
   apocryphal, baseless, counterfeit, disputed, exploded, fabulous, false, fictitious, spurious, unauthorized

2. Eric Hawkins:

   We need to examine the role and responsibility of law enforcement and other state agencies that protect people... it's fair for that examination. We expect it, but it's also important that people understand that sometimes it's not as easy, not as obvious, at the very outset or during the course of the investigation, to resolve these sorts of incidents. You have people absolutely determined to secrete a child away unlawfully, hiding under a staircase, giving limited access to the home, and otherwise evasive in terms of cooperation. Having someone who's that determined, and( police) don't have legal justification to do certain things, it makes it difficult to resolve cases.
