I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
Physical evidence was always extremely important. What has changed with technology is what types of evidence are more commonly examined. It used to be hairs and pollen and now it's touch DNA and cell phones.
I may not be the best to ask since I'm not really on the front lines, I come in after the action is over, but in my opinion, yes. You don't get criminal masterminds in real life.
If you want to be a DNA analyst you may need a Masters or PhD in genetics, depending on the requirements of the agency or facility. Check vacancy postings at professional organizations, such as https://webdata.aafs.org/public/jobs/postings.aspx and https://www.theiai.org/job_listings.php.
Best of luck!
I don't believe so (in fact I believe I address this question during an autopsy scene in my book Perish) but you'd have to ask a pathologist. Sorry I can't help.

I'm not sure what you mean: a) how long after a print is left will ninhydrin still detect it, in which case I can say from my own experiment that there's little rhyme or reason to this, sometimes older prints develop better than newer ones or vice versa, or b) how long does a print developed with ninhydrin last, and the answer to that is that ninhydrin is a dark purple dye, so it is permanent, though it will continue to develop so that the entire page may eventually turn purple so we use a fixative chemical on the now-visible print so that will stop the ninhydrin from darkening the paper further. I hope that helps!
