This entire subject comes down to democracy at the core, in which every person is allowed to put in an opinion. At the same time, people need to realize that with 300 million (plus) people in this country, it's hard to put in a solid opinion that is considered "right" by the majority. By the way, that's all you're going to please, is the majority. You will literally never have every single person in this country completely agree on one subject.
Now as the trial went, who would or would not stop and at least ask what a person is doing, following them (jumping on them in aggression is a different story, but what would you do?). What would you do if you were being attacked? All of these questions fall to separate individuals in a situation, with completely different mentalities.
Now, as a country, we have to figure out what the fine line between self defense and "murder" is. Put every individual's thoughts on a single page. Get ready to read for months.
Most tend to follow "wise" statements that they read first, either "it was wrong" or "it was right" because of the "following evidence". But, no one but the two individuals involved can actually state what was going on in their minds, and what they were thinking of doing.
Misinformation that we are fed should be a red flag, as no one but those involved can actually know what happened. This is nothing more than a debate that may be argued for all time, in the society we have at least.
