Is a prosecutor improperly vouching for the credibility of an arresting officer?

Appellant further contends the prosecutor improperly vouched for the arresting officer's credibility by describing him as a "professional." However, "'so long as a prosecutor's assurances regarding the apparent honesty or reliability of prosecution witnesses are based on the "facts of [the] record and the inferences reasonably drawn therefrom, rather than any purported personal knowledge or belief," her comments cannot be characterized as improper vouching.' [Citations.] Misconduct arises only if, in arguing the veracity of a witness, the prosecutor implies she has evidence about which the jury is unaware. [Citations.]" (People v. Fernandez (2013) 216 Cal.App.4th 540, 561.)
