Respectfully Snipped
I agree with most everything you have offered with the above exception.
While I believe violation of due process will be argued by the defense, I do not believe that the prosecution's evidence would be deemed inadmissible. I believe instead that the defense would be allowed to place into record the fact that they were not afforded the right to independent analysis.
Arizona v. Youngblood (1988)
"Unless a criminal defendant can show bad faith, the State's failure to
preserve potentially useful evidence--of which no more can be said than that it could have been subjected to tests, the results of which might have exonerated the defendant--does not constitute a violation of the due process clause of the United States Constitution's Fourteenth Amendment."
State v. Estep (1991)
"The Due Process Clause of the Fourteenth Amendment does
not require the prosecution to preserve samples for independent analysis unless the sample possesses an exculpatory value that is apparent before the sample is destroyed, and the defendant is unable to obtain comparable evidence by other reasonably available means.
The above cases were also cited as precedence for State v. Abercrombie, (2007), in which a trial court granted defendants motion for an independent lab analysis. However, due to the reported weakness of the sample, the forensic testing did not allow for an independent test. The jury convicted the defendant on felony murder, which was subsequently appealed based largely on the inability of the defense to have access to the States evidence for independent analysis, claiming denial of due process. Ultimately, the State Supreme Court found that "there was no evidence that the consumption of the DNA evidence by the States testing was the result of bad faith." The conviction was upheld.
