You could say: our means of increasing faith in justice is to tell everyone that miscarriages occur all the time, even if they maybe don't, so that good ordinary Americans will become more and more concerned and prevent miscarriages, which will increase faith etc.
This is a very complicated and indirect way of purportedly getting the result you want.
However, if you wanted exactly the opposite result - that is, you wanted to decrease faith in the criminal justice system - what would you do? Answer: give as much publicity as possible to miscarriages of justice, purported or real.
Which is exactly what you're doing, right? Have you ever heard the thing about what to do when you're in a hole?
Also, I'm quite aware that Americans aren't Japanese. On the other hand, I seldom hear that awareness from people who point out how much better urban life is in, say, Reykjavik rather than Detroit. And appear to believe that the problems of Detroit can be solved by adopting the ideology and/or governance structures of Reykjavik. (Which, in fact, has pretty much already happened - if anything, the flow is in the other direction.)
As for throwaways: stay on the reservation, and you'll have nothing to fear. Duck under the barbed wire, and you'll find out...
