CMV: Shows which depict the prosecution/investigators as always right, as well as forensic shows which misrepresent forensic science as infallible (and pseudo-scientific often, have led to a perversion of the justice system, such as NCIS, Criminal Minds, CSI, Bones, etc.

Many shows likes Criminal Minds, CSI,  NCIS, Bones, Cold Case Files, *(ad nauseum)* , always "get their man" so to speak. 

I feel this like this biases the general public against primary suspects (not charged with anything *yet*) and defendents (on trial). The idea that forensic science is infallible and incapable of any errors (human or otherwise)  lowers the average personal level of confidence required to find someone guilty of a crime (beyond reasonable/showdow of a doubt). 

This had led to a perversion of the justice system.

Your view is part of what is referred to as "the CSI effect", though it's the less prevalent belief.  The larger part--the part that is widely believed by lawyers--is also sort of the opposite. The notion is that the shows you're talking about always have conclusive forensic evidence or a confession.  So, the belief goes, these shows are training juries to expect a higher standard of proof before they are willing to convict.

Studies on the CSI effect have failed to show any significant evidence for it in terms of links between watching these shows and having preconceptions about forensic evidence.  Studies *do* show that over time people tend to expect and demand more of scientific evidence and trust it more when it is present but they have been unable to find a link to viewership of these shows or the "always get their main" aspect to which you refer.  Based on studies it actually appears to just be a "tech effect" which is essentially that as technology improves people expect forensic technology to improve also.  It also seems to be the case that if forensic shows are contributing to this at all it's merely on account of showcasing technology of which the public was previously generally unaware.
