A quick verdict is usually a guilty verdict.
I was once on a jury that acquitted in 15 minutes. We were actually pissed off that the case even made it to trial in the first place.
How quick did Freddie Gray jury come back? That was a shocker.
A good point...
Remember the first trial for officers involved in Rodney King case? The jury took seven days to decide not to convict...
