(i) whether there is evidence of the existence of criminal conduct;
(ii) the nature and seriousness of the problem or alleged offense, including the risk or degree of harm from ongoing criminal conduct;
(iii) a history of prior violations of the same or similar laws and whether those violations have previously been addressed through law enforcement or other means;
(iv) the motive, interest, bias or other improper factors that may influence those seeking to initiate or cause the initiation of a criminal investigation;
(v) the need for, and expected impact of, criminal enforcement to:
(A) punish blameworthy behavior;

(D) reinforce norms embodied in the criminal law;
(E) prevent unauthorized private action to enforce the law;
(F) preserve the credibility of the criminal justice system; and
(G) other legitimate public interests.

(vii) the collateral effects of the investigation on witnesses, subjects, targets and non-culpable third parties, including financial damage and harm to reputation
(viii) the probability of obtaining sufficient evidence for a successful prosecution of the matter in question, including, if there is a trial, the probability of obtaining a conviction and having the conviction upheld upon appellate review; and
