It affects the jury. If the jury watches tv shows that builds the expectation that there is always a bunch of ballistics evidence etc and that it is always fool proof then they will 1) distrust when there isn’t that type of evidence (but enough other evidence) and 2) they will overvalue the evidence when it exists

It affects everybody. I've heard of people arrested in rather more oppressive regimes expecting to be Miranda'd because it's what they know from American cop shows and they thought it was broadly applicable everywhere.
