Since a jury trial requires a unanimous vote to convict, it's not a risk at all to be tried by jury in an innocent plea. It only takes one vote and as has been mentioned here a couple times, Jodi Arias is prime example of how that can work to the defendants benefit. There are many more.
Jian Ghomeshi elected judge alone. He's guilty.

The disadvantage of trial by jury is that the verdict can be appealed by both the suspect and the prosecution, and a new trial set. This can go on for years, much like the Amanda Knox and Raffael Sollecito trial. An appeal of a Judge alone verdict is unlikely (correct me if I'm wrong) to be appealed and, as a result, land on a jury's lap.
Trial by Judge alone fast tracks the process, much like Rudy Guede in the murder of Meredith Kercher. In any case, the decision for trial by jury means that both the suspect and prosecution can appeal a verdict (on valid legal grounds), and the suspect can do it all over again and again (dragging out the process), and then appeal up the chain, albeit at his own expense, potentially to the Supreme Court, like the murderers of Victoria Stafford. He's looking for every possible exit.
Jian Ghomeshi, on the other hand, is without doubt, responsible for some problematic activities that violate the law - yet he's going to most likely argue that the "culture" of the CBC enabled him to get out of hand ... just a guess.
I don't actually have an Opinion on the guilty/innocent pleas vs. judge/jury, I was just trying to explain someone else's post because I understood what they were trying to say
I agree, it is just a theory. Nothing is Concrete. I'm sure there are Many examples of Guilty choosing judge and innocent choosing jury.
