Blair, the Metropolitan police commissioner, has signed off a report by his force’s traffic unit which shows that black people account for 46% of all arrests generated by new automatic numberplate recognition (ANPR) cameras.
Although ANPR technology is impartial, the disproportionate number of blacks being arrested has prompted the Met to investigate.
The arrests have been broken down by ethnicity in a report sent last month to the Metropolitan Police Authority (MPA), to which the force is accountable.
It reveals that between April 2005 and January this year the units generated 2,023 arrests. Of these 923 were black suspects, while 738 (36%) came from white backgrounds. Asians accounted for just over 9% of arrests. ... However, statistics from the 2001 census show that the highest black population in any borough is no greater than about 25%. The proportion of black people across the capital as a whole is about 11%.
