In Season 2 Episode 2 of The Wire at around 31:30, we see a guy (forensic medical examiner?) use a slide rule. Why not use a normal electronic calculator? I'm not really familiar with the show - is there some reason in the show why he would have a slide rule?
Here is my theory - is this off-base? I understand that the show's writers went to great lengths to depict everything realistically. I also know that forensic medical examiners use custom-made nomographs and sliding calculators to make quick calculations without having to memorize formulas and do math by hand. (See for example https://www.google.com/search?q=forensic+nomogram) These are stripped-down ultra-simplified single-purpose calculating instruments which sometimes have sliding parts, but are not slide rules. Slide rules are complicated general-purpose calculators and much harder to use.
So maybe the writers heard from somewhere that forensic medical examiners use sliding calculators, and either they or the props people misunderstood and gave the guy a real old-fashioned slide rule instead?
Any chance the writers ever mentioned this in interviews?
