It is important to bare in mind that when investigating the gangs matrix database the Information Commissioner warned that the system had led to denial of services and other adverse consequences as the matrix often failed to distinguish between victims and offenders of crime. This has effectively led the gangs matrix to generate the same exact same outcome for some vulnerable youngsters in London that it aims to protect against, in fact pushing more young black men to be in gangs rather than away from them, it could in essence be reverse gang grooming. There have been numerous cases of concern with the gangs matrix, wrongful arrest, unjustified threats of eviction, wrongly seizure of vehicles, bans from extracurricular education centres, and a horrible case of a boy's mother being put into a care home while he was denied the status of her carer as he was wrongly placed on the database.
The database is already racially biased, so if you are a black male from an economically deprived area you are automatically more likely to be on the database, if you live near or go to school with someone in a gang you are then increasingly likely to added to the gangs matrix, which could lead to the denial of services, such as housing, social care and in one case basic benefits such as a driving license. On top of this black men are more likely to be racially profiled in London; with all this guilt by skin colour, guilt by association and possible police harassment, the police are giving economically youths no choice but to join gangs. Baring in mind that the databases often falsely lists victims of gang violence as perpetrators, if you are especially vulnerable, from a deprived area, cannot access housing or social services, and more likely to be harassed by police, the gangs matrix is more likely to add to gangs than to effectively police them.
