Why is it better one way or the other depending on the focus of society? I don't see the connection. I'd equally lose faith in the system either way. Maybe moreso if I see my neighbor going to jail unjustly rather than some random individual. As for the other way around, seeing a guilty man go free, the standard for imprisoning someone being evidence beyond reasonable doubt seems reasonable. Granted, there is a two tier justice system and if you are unreasonably wealthy, you have more leeway, but I think that's a different discussion.
