"Sure, I committed a double murder back in 1977, was convicted of it, and my conviction was affirmed on appeal. But guess what? That was 45 years ago, and you guys in San Diego can't find the trial transcript at this point. So you can't prove that I personally committed the murders, which means I get released!"
Court of Appeal: "Yep. That's right."
I certainly hope that they lose the trial transcript if I ever commit a double murder as well. Wow.
Just a hint: You might want to hang on to this stuff. Kinda important.
