True, apparently I got backspace happy when Inposted the reply on mobile. I was talking about the belief by a perspective juror that law enforcement personnel are more credible or trustworthy than others due to their status as law enforcement personnel.

This is not quite true. The rules of evidence state that law enforcement (official) testimony is more credible than civilian testimony. Officials have a wide exemption from hearsay objections, if the offfical was working at an official task at the time.
