Does a promise of leniency from a detective at trial and on appeal in a sexual assault case affect the credibility of a witness at trial?

At trial and on appeal, Wall argued that the detectives provided an improper promise of leniency when they told Wall he was at a crossroads and if he took one pathi.e., if he told the truthhe could "go on with [his] life" and "be with [his] wife and child and start fresh." According to Wall, these statements were more than "proper exhortations to tell the truth" ( People v. Holloway (2004) 33 Cal.4th 96, 115, 14 Cal.Rptr.3d 212, 91 P.3d 164 ) and did not "simply indicate[ ] a willingness to listen to defendant and encourage[ ] him to tell what happened" (
