"The figures also show 25% of victims were black - the highest proportion
since data was first collected in 1997."

"For every 100,000 people in the capital, there were 168 knife offences
in 2017-18, with separate figures, from the mayor's office, showing that
young black and minority ethnic teenage boys and men were
disproportionately affected, as both victims and perpetrators."

"From 2009, the number of stops fell sharply across England and Wales,
especially in London, primarily because of concerns that the measures
unfairly targeted young black men, wasted police resources and were
ineffective at catching criminals."

Ale generalnie wydaje sie, że wiele czynników na raz, tym bardziej, że
dane obejmujące okresy dłuższe (od 1998 i wczesniej) pokazuja pewna
cyckliczność, czy powolne fluktuacje.
