I have no idea of the politics of the murdered man. On the whole NJ is a very left leaning state, and isolated incidents that show the folly of their policies are not going to infuse sense into the bulk of the populace. People like anti-gun Christie are elected for a reason - that reason being that he represents the preferences of the majority of the voting population.
If that evil were not among us crime would drop 80% to 90%.
The left has been hiding, excusing, or blaming whites for black crime for the past fifty years. The failure of the great percentage of American blacks to adapt to modern civilization has been a shock for liberals who believed blacks would quickly ascend to white levels after the passage of the 1964 Civil Rights bill. I was one of those misguided believers. It didn't happen.
While millions of competent blacks have risen, there remains a huge, violent, government-dependent, black underclass that resists all efforts to civilize it. Steps must be taken to eradicate the black underclass i.e sterilization. But few have the guts to attempt it. If nothing is done, we're looking at fifty more years of black pathology or a race war. I don't want either.
