Only in a system where judges are elected, like the US. Many, if not most European countries (to discuss the examples I'm familiar with) appoint judges and have had a jury trial system until the beginning of the 20th century. It was abandoned after it was found to be easy to manipulate on a regular basis. Jury trials degenerated into character trials - prosecution would try to discredit the accused, and defense would try to paint him as a pillar of the community. Juries placed too much weight on their personal feeling towards the accused, and too less on what happened and what the evidence was.
We like to hope that the US system solved this problem, of course.
