You chose to specify by ethnicity that irresponsible black men that ignore their familial duties are at fault for crime in Britain. While absent parents are a reason for crime, the
responsibility of the larger community should be adressed, such as discrimination and ostracization. Young black people commit more crimes associated with poverty, and are the most victims of violent crime.
Discrimination and exclusion puts minorities in disadvantage from school days to work and dealing with housing, local communities and the police. Black people are disproportionately more subject to stops and searches by the authorities. The
Home Affairs Select Committee found that black people are over-represented at all stages of the criminal justice system. The government has a page for the
conviction ratio for different types of crimes, according to ethnicity. As you can see, whites are always near 100% conviction ratio, which likely means that white people crimes are ignored until they're serious or caught red-handed, while people of other ethnicites have a lower threshold of burden of proof to be arrested.
Wikipedia tells me that the white british are the major culprits of hate crime, terror crimes, sexual grooming and child sex offenses. I imagine that the majority of white collar crimes also falls upon white british.
P.S.: I know this is off-topic, but certain perceptions should be adressed so that we avoid the pitfalls of prejudice, discrimination and dehumanization.
