It's good to see the truth is coming out, there were many warnings to the park and police concerning these problems. Orlando just wanted to be left alone, he didn't instigate the interactions, he only responded to actions against him. This is  apparent by the Sheriff NOW increasing patrols at the park. If Orlando was the only problem, there would be no reason to increase patrols now that he has passed away.
I'm not saying Orlando is not responsible for his actions, he used the gun and took the life. The life he took was probably a person not responsible for past interactions with Orlando. Was not responsible for pushing him to his limit.
