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.
That’s really a question for a pathologist, but apparently lividity develops before rigor, so it shoudn’t shift much after rigor has set in. However that can vary depending on temperature and physical/medical conditions. Blood will pool following the law of gravity but if the legs were bent, restricting the blood vessels, then it might pool in the torso. Sorry I can’t be more help.
I don't see why not, it's rigid and would hold a shape. It's a very small item and somewhat brittle, though. I would think it would be tough to bite all the way through one. You'd probably be better off swabbing it for DNA of the biter.
I’m sorry but I can’t. That’s a question for a toxicologist. I don’t know anything about drug chemistry.
Before I worked in forensics, I was a personnel secretary, a hotel maid, and an ice cream counter server and a gas station 'full service specialist'. My husband is an elevator field engineer. There is 'politics' in every profession. Every. Single. One.
Best of luck!

Because that's not our job. That's the detective's job. They're in charge of and responsible for the investigation.
Any agency can use whatever requirements they want, so some (like mine) require only a high school diploma (but give extra points for advanced degrees, so we all have degrees). Some might require a Bachelor’s in any subject but give more points for forensic training—or not. The only way to know is check their job postings. Best of luck!
I don't believe so, but I haven't done DNA analysis in 20 years so I'm not the best person to ask. I know there's an amylase test for saliva, but I don't know if it's used any more. And if you have a mixture I doubt it would be possible to tell what DNA is from what bodily fluid.
