Short version: -Pujols (the puncher) was doing his job, managing a coffee joint.
77 yr old white guy complains about food or service or something, and calls Pujols (27 yr old black man) a particularly nasty racial slur.
-Pujols asks him to repeat that. Geezer does.
-Pujols cold-cocks the geezer and drops him to the concrete floor, and old guy dies of head injuries later.
-Pujols pleads guilty to felony battery and gets two years house arrest, 200 hours of community service, and has to take an anger management course.
Here in the States, provocation is a gray area in law. Usually, it doesn't get you off the charge, but it might soften your sentence as a mitigating factor.
I personally think that provocation (provisionally meaning to act in such a way that would incite a violent reaction) should be treated more like an assault (provisionally meaning to put someone in fear of an imminent fight), and the first physical shot would be preemptive self-defense. In that view, Pujols was judged too harshly. But the racist senior citizen was 50 years senior to the young Pujols, and generally a young, strong guy should have the wherewithal to hold back from beating on an old man, perhaps just treating him like a senile coot whose outrageous behavior is somewhat tolerated. But then this guy has a lifelong history of horrifyingly sick criminal behavior, not just some "relic of his time". So where does this fall on the spectrum? It's an interesting question of what has the most moral weight.
