Grapeboi used his vast knowledge of the US legal system to defend Zimmerman
Not vast knowledge. Literally first few weeks of a 9th grade US law course kinda stuff. Which is why it surprises me that Skully still argues the legal aspects of that case. There is certainly a strong ethical and moral argument to be made that GZ deserves some sort of punishment, but the criminal case was a non-starter within the confines of the actual law. Which is why the DA didn't want to touch it.
and was claiming that Skully and I never graduated high school.
No- I just said that Skully didn't. Try to keep up, I threw you a few bones already by clearly saying that I quoted Skully, and that I would not expect someone who did not grow up here to understand those things. If I were to move to any other foreign country, I would probably be ignorant to the principals of their legal systems as well, unless I actually put in the effort to understand it.
Even then, I would still not really understand their legal system the same way that an actual native born citizen does, because there is also a cultural and historical context that is woven into it. Kinda like you and the US constitution.
