The thing about jury’s is that people use their morals. If they don’t think a the crime should be a crime they may not want to comvict them even tho they know the person broke the law.
If I’m sitting on a Jury for someone arrested for feeding the homeless I will never vote to convict even if the evidence is as clear as day.
I’m not comparing shooting people to feeding the homeless buy just showing an example of why people don’t vote to convict when the evidence is clear.
