Was Henry Nowak a victim of two tier policing?

 

Some Sikhs who live in Southampton have said that they are afraid to go out since the stabbing of Henry Nowak by Vickrum Digwa. Statistically, white people who live in Britain aren't at risk from Sikhs living in Britain, they are more at risk from their own kind. They are at more risk of dying when they're crossing the road.

What evidence is there for two tier policing? Most of it seems to be based on conjecture or the bias of politicians and hack journalists, who have their own political agenda to pursue. The data suggests that black people are still disproportionately more likely to be stopped by the police when going about their business than white people. In Southampton, black people are five times likely to be stopped by the police.

What happened to Henry Nowak was dreadful and the police made a complete cock up of it. They initially believed Digwa but not Henry Nowak, who told them that he'd been stabbed and that he couldn't breathe. One police officer can be heard saying, "I don't think so mate." But If the police were carrying out two tier policing in Southampton, why is Vickrum Digwa, now serving a 20-year jail sentence?
