The *government crime lab* (prosecution) destroyed the evidence
re 3) So you're now alleging that *Hillary* covered something up in the sexual misbehavior of Bill, rather than being an uninformed spouse defending her husband?
re 5) Above you said 'because the rape evidence had become "lost" [while in HER custody]', implying per personal possession. Now you admit that your sources don't say when it was lost, or by who. It could have been lost by the police. It could have been lost by the independent lab. It's pretty unlikely that it was lost by the defense attorney, as they are not allowed to hold evidence for very good reasons. For Hillary to be blamed for this, it would have to proven that she turned either the police or the lab to illegal behavior.
But turns out the story is completely different than that. The police lab cut the evidence (a bloodstain) from the defendant's underwear, and after blood testing (not DNA, this is 1975) ended up tossing out the bit of material. So when the defense (Clinton) asked for the underwear to test (as required by her duties as public defender), there was nothing to test. The government lab had destroyed the evidence, collecting only a blood type, and it was their incompentence that let the defendant plead guilty and get a lighter sentence. (https://www.youtube.com/watch?v=e2f13f2awK4&feature=youtu.be, Hillary Clinton being interviewed about the case.)
Then you go onto the notion of defeating a polygraph test, but again offer no proof that Clinton coached the defendant to do so.
