2pac didn't know they were cops!! He even said that. He saw 2 crackers harasing a black man, he intervened, they pulled a gun and he pulled his gun. He did what I HOPE all of us would do. It just turns out they were crooked cops. He didn't pull up at a traffic stop with blue lights on and started blasting. Context of statements matter. I can easily tell you, "hey, I beat an olympic gold medalist track star in a race", but if I race that track star when he/she is 60 years old, is it really the same?
