My first issue with the ‘statistics’ posted by ThatJadeMaker is that they are sourced from Wikipedia. Wikipedia has its uses but it isn’t generally a suitable source for serious issues. If the Wikipedia entry uses appropriate sources then you need to tease them out and identify them.
Assuming these statistics are credible, are black people in London involved in violence because it’s a nice way to pass the day? Do they just enjoy fighting, stabbing and shooting? Or is the violence linked to drug dealing and gangs fighting to control the lucrative drug trade?
The next point some racists make is along the lines of black people being inherently associated with antisocial behaviour like drug dealing, missing out the link to deprivation. The inference is that it’s something to with the genetics or culture of black people. Drug use is high in many deprived communities in western countries, regardless of ethnic make-up. While there is a lot of wealth in London, there is also a lot of deprivation. Black people are unfortunately not well represented among the wealthy but are among the deprived.
Many people in deprived communities, especially men, don’t have the role models to show them that it is possible for people like them to have a job with good financial rewards, not as financially rewarding as drug dealing but much safer. Instead young impressionable boys are dazzled by the idea of great wealth at a young age, with social media ramping up the desire to ‘make it big’.
These pressures are not restricted to black boys, though they do have to deal with additional issues like not feeling accepted by the wider community, causing them to turn inwards, and low expectations at school. In London, the example used by ThatJadeMaker and MissKitty0, because black people are underrepresented in the super-wealthy and high earning professionals category (the main people that can afford to live in London other than social housing tenants), the proportion of the black population that is deprived is much higher than the proportion of the white population that is deprived and there is therefore a greater involvement in the drug business and the associated violent crime.
